Not verified in this report

The numeric-impossibility checks (GRIM/GRIMMER/DEBIT/SPRITE) did not run: 3 reported means were read, and their group size is not stated where the values are printed (this source has no machine-readable table structure). These checks need the count the mean was averaged over, so none was performed.
No data or code availability links were detected to verify.

Biggest issues

01Efficacy rests on an unvalidated surrogate endpoint
highOverreachreviewer-assessedFull detail
The primary endpoint is a decrease in SOFA score, which is a surrogate for clinical outcome. The paper acknowledges this in the limitations: 'the primary end point of a change in SOFA score is a surrogate outcome, so future adequately powered trials should test these strategies on patient-centered outcomes.' Although the paper cites prior data linking a 1.4-point SOFA decrease to reduced 28-day mortality, it does not demonstrate target engagement at the tested dose (e.g., PK/PD or dose-exposure) for the drugs used. Therefore, the surrogate is inadequate as a basis for the efficacy claim.
“the primary end point of a change in SOFA score is a surrogate outcome, so future adequately powered trials should test these strategies on patient-centered outcomes.”
02Treatment effect not shown to be clinically meaningful
highOverreachreviewer-assessedFull detail
The primary effect is a 17.2% absolute increase in the proportion of patients achieving a ≥1.4-point SOFA decrease (35.1% vs 17.9%). While statistically significant, the clinical meaningfulness is not anchored to a minimal clinically important difference or a patient-centered outcome. The paper notes that mortality was not significantly different, and the effect is on a surrogate endpoint. The magnitude is not explicitly anchored as clinically material.
“The SOFA decrease end point was attained by 46 of 131 patients (35.1%) in the precision immunotherapy group and by 26 of 145 patients (17.9%) in the placebo group (difference, 17.2% [95% CI, 6.8% to 27.2%]; P = .002).”

This Kaimen Rigor review uses Kaimen Rigor reviewers trained on a curated corpus of high-fidelity and retracted papers, with expert supervision and curation. It can still make mistakes; verify each finding against the source before relying on it.

This is a well-conducted randomized clinical trial with rigorous design, clear reporting of ethics, and transparent statistical analysis. The main weakness is the vague data sharing statement, which lacks a concrete access mechanism. Minor copyedit issues and a small internal discrepancy in a secondary endpoint count do not undermine the overall robustness.

Both reviewers classified the study as interventional, and this was adopted. The evaluation covered all eight dimensions; non-applicable sub-criteria (e.g., animal housing, cell line authentication) were excluded. The statistics verification covered only a subset of tests (those with test statistics and df or effect estimates with CIs); exact p-values and threshold-only p-values were not machine-verified. The integrity check flagged a minor internal contradiction in a secondary endpoint count (51 vs 52 patients), which is noted but does not affect the primary endpoint.

Numerical inconsistencies

1 finding · worst low

Values that contradict each other or are impossible for the stated sample: recomputed p-values and test statistics, GRIM/GRIMMER checks on summary numbers, percentages against their own counts, totals against their parts, and estimates against their own confidence intervals.

Internal contradictions in the reported numbersAssessed

Recomputed 10 tests: 10 consistent, 0 inconsistent; 10 via agent-written checks.

Overstated conclusions

Eight Dimensions7 pass · 1 warn

The introduction cites prior RCTs that failed due to heterogeneity, and references recent data on immune stratification using ferritin and HLA-DR. The rationale for targeting macrophage activation-like syndrome and immunoparalysis is well-supported by prior studies. Limitations of prior work are implicitly addressed by the precision design, though not explicitly detailed.

Per reviewer (2) — the votes behind the verdict

PASSReviewer 1· 90% conf

The study clearly establishes its scientific premise by citing prior work on sepsis heterogeneity and the need for precision immunotherapy, and it explains how the current study addresses limitations of previous trials.

Evidence

“Sepsis is heterogeneous, and the optimal strategy for tailoring immunotherapy is uncertain.”

Introduction ¶1

paraphrase[Introduction, paragraph 1]

“As such, a precision approach to immunotherapy in sepsis may be necessary, relying on rapid, accurate classification of the immune dysregulation using biomarkers.”

paraphrase[Discussion, paragraph 2]

“First, precision immunotherapy for severe infections has been increasingly considered since the COVID-19 pandemic: a strategy of anakinra treatment guided by soluble urokinase plasminogen activator receptor concentrations as a biomarker of lung hyperinflammation has been registered by the European Medicines Agency and for Emergency Use Authorization by the US Food and Drug Administration for treatment of patients with COVID-19 with pneumonia.”

PASSReviewer 2· 95% conf

The paper establishes a clear scientific premise by citing prior research on sepsis heterogeneity and immunotherapy, and provides a logical rationale for the precision approach.

Evidence

paraphrase[Introduction, paragraph 1]

“Many randomized clinical trials (RCTs) studied immunotherapies but failed to demonstrate an improvement in outcome. This is likely related to the heterogeneity of immune dysregulation, which varies from hyperinflammation to immunosuppression.”

paraphrase[Introduction, paragraph 2]

“Recent data suggest that patients with sepsis with shock can be classified by using blood ferritin concentrations and the expression of the human leukocyte antigen (HLA) DR on monocytes into 3 strata of immune activation.”

paraphrase[Introduction]

“The paper does not explicitly discuss limitations of prior research, but the precision approach is presented as a solution to the heterogeneity problem.”

Randomization was computer-generated with 1:1 allocation, and blinding was double-blind with unblinded pharmacists. A priori sample size calculation was provided. Inclusion/exclusion criteria were pre-specified. Outlier handling is addressed through the analysis population and missing data imputation. Controls are the placebo group.

The study design is robust, detailing randomization, blinding, inclusion/exclusion criteria, and a power analysis. It is a well-conducted clinical trial.

Evidence

paraphrase[Methods, Randomization and Allocation, paragraph 1]

“Enrolled patients were randomized 1:1 into groups: (1) intervention strategy: standard care and precision immunotherapy, and (2) control strategy: standard care and placebo immunotherapy, using separate randomization per study site with the aid of a computer-generated sequencing ( Figure 1 ).”

paraphrase[Methods, Randomization and Allocation, paragraph 3]

“Except for the unblinded pharmacists, the investigators, attending physicians, nursing personnel, and participants remained blinded to the assigned intervention.”

paraphrase[Methods, Sample Size Calculation, paragraph 1]

“The study was powered for the primary end point anticipated to be attained in 40% in the intervention group and in 20% in the control group. At the significance level of 5% and a power of 90%, the calculation yielded 117 patients per trial group. Considering a dropout rate of about 15%, 280 were needed.”

The statistical analysis is well-described, naming tests, reporting exact p-values, and providing effect sizes with confidence intervals. Data presentation is appropriate for a clinical trial.

Evidence

“Comparisons for primary and all secondary end points were calculated by the Fisher exact test; the odds ratios (ORs) and 95% CIs by the Mantel-Haenszel test. A confirmatory model for the primary end point included a stepwise logistic regres- sion for the proportion who achieved at least a 1.4-point de- crease in SOFA score by day 9 as the dependent variable, with the blinded intervention, baseline CCI, SOFA score, and study site as the independent variables. Kaplan-Meier and Cox re- gression analyses reporting hazard ratios (HRs) with 95% CIs were used to illustrate survival. The time to reversal of SIDF was compared by Cox regression analysis. Comparisons of the state of infection by day 15—defined as resolved, intermedi- ate, treatment failure, or superinfection—were conducted by ordinal regression analysis.”

“This trial has several limitations. First, the primary end point of a change in SOFA score is a surrogate outcome, so future adequately powered trials should test these strategies on patient-centered outcomes. Second, the measurement of ferritin and HLA-DR measures may not be feasible across hospitals, and the complexity and assay time could limit scaling and implementation. It is notable that average time from sepsis onset to when the study drug was first administered was 36 to 48 hours. Third, the stability of macrophage activation–like syndrome and sepsis-induced immunoparalysis subtypes over time de- serves further study. Fourth, the study findings are general- izable only to patients with sepsis with pneumonia or bacter- emia, and other etiologies of sepsis were excluded.”

Kaimen Rigor Action ItemsFinal pass before journal submission

The published work is robust and well-reported, with only minor reporting gaps. An informed reader should weigh the vague data sharing statement and the minor internal discrepancy in a secondary endpoint count. These do not warrant a correction but suggest that the data sharing statement should be clarified in any future version or erratum.

1.
HIGHdata code
In the Data Sharing Statement section, replace 'See Supplement 4' with a concrete access route, such as a data access committee or repository, including contact details and conditions for access.
The current statement is vague and does not specify how data can be obtained, which is a reporting gap for a clinical trial.
2.
HIGHdata code
If possible, deposit de-identified aggregate data in a public repository with a DOI or accession number, and mention this in the Data Sharing Statement.
A public repository deposit would strengthen data availability and transparency.
3.
HIGHdata code
If custom analysis code was used, share it in a public repository with a persistent identifier and reference it in the Data Sharing Statement.
Code sharing is not mentioned, and providing it would enhance reproducibility.
4.
MEDIUMreporting
In the Results section for the secondary endpoint '>=1.4-Point decrease of mean SOFA score d 2 to 15', reconcile the discrepancy between the text (51 of 131) and Table 2 (52 of 131).
The internal contradiction, though minor, could confuse readers and should be corrected in an erratum or clarified.
5.
MEDIUMcopyedit
In the Abstract Results, remove the unmatched closing parenthesis after '[33.7%]'.
The extra parenthesis is a punctuation error that should be fixed.
6.
MEDIUMcopyedit
In Methods, Randomization and Allocation, fix the hyphenation error 'vol-ume' to 'volume'.
The hyphenation error is a typographical issue that should be corrected.
7.
MEDIUMcopyedit
In Methods, Statistical Analyses, rephrase 'The primary analysis included all patients randomized, who did not withdraw their consent or requested removal of all data.' to 'The primary analysis included all randomized patients who did not withdraw their consent or request removal of all data.'
The original phrasing is awkward and could be clarified.
8.
MEDIUMcopyedit
In Table 1, remove the duplicate row for 'SOFA score e 10 (7-12) 9 (6-11)'.
The duplicate line is a formatting error that should be removed.
9.
MEDIUMcopyedit
In Table 2 footnote a, replace 'kidney' with 'renal' for consistency with the main text's SOFA score description.
Terminology inconsistency between the table and text should be harmonized.
10.
LOWcopyedit
In Methods, Trial Design, add 'and' before 'the General Data Protection Regulation' for better flow.
The conjunction improves readability.
11.
LOWcopyedit
In Table 1 footnotes, ensure consistent capitalization for sentence fragments (e.g., 'Self-reported', 'Refers', 'The').
Capitalization inconsistencies are minor but should be standardized.
12.
LOWcopyedit
In Table 2 footnote b, improve punctuation by replacing the semicolon after 'blood draws' with a period or comma for clarity.
The current punctuation is awkward and could be clarified.
13.
LOWcopyedit
In Table 3 footnote a, ensure consistent spacing around commas and between graded terms and their definitions.
Inconsistent spacing is a minor formatting issue.

Kaimen Rigor Action ItemsFinal pass before journal submission

1.
HIGHdata code
In the Data Sharing Statement section, replace 'See Supplement 4' with a concrete access route, such as a data access committee or repository, including contact details and conditions for access.
The current statement is vague and does not specify how data can be obtained, which is a reporting gap for a clinical trial.
2.
HIGHdata code
If possible, deposit de-identified aggregate data in a public repository with a DOI or accession number, and mention this in the Data Sharing Statement.
A public repository deposit would strengthen data availability and transparency.
3.
HIGHdata code
If custom analysis code was used, share it in a public repository with a persistent identifier and reference it in the Data Sharing Statement.
Code sharing is not mentioned, and providing it would enhance reproducibility.
4.
MEDIUMreporting
In the Results section for the secondary endpoint '>=1.4-Point decrease of mean SOFA score d 2 to 15', reconcile the discrepancy between the text (51 of 131) and Table 2 (52 of 131).
The internal contradiction, though minor, could confuse readers and should be corrected in an erratum or clarified.
5.
MEDIUMcopyedit
In the Abstract Results, remove the unmatched closing parenthesis after '[33.7%]'.
The extra parenthesis is a punctuation error that should be fixed.
6.
MEDIUMcopyedit
In Methods, Randomization and Allocation, fix the hyphenation error 'vol-ume' to 'volume'.
The hyphenation error is a typographical issue that should be corrected.
7.
MEDIUMcopyedit
In Methods, Statistical Analyses, rephrase 'The primary analysis included all patients randomized, who did not withdraw their consent or requested removal of all data.' to 'The primary analysis included all randomized patients who did not withdraw their consent or request removal of all data.'
The original phrasing is awkward and could be clarified.
8.
MEDIUMcopyedit
In Table 1, remove the duplicate row for 'SOFA score e 10 (7-12) 9 (6-11)'.
The duplicate line is a formatting error that should be removed.
9.
MEDIUMcopyedit
In Table 2 footnote a, replace 'kidney' with 'renal' for consistency with the main text's SOFA score description.
Terminology inconsistency between the table and text should be harmonized.
10.
LOWcopyedit
In Methods, Trial Design, add 'and' before 'the General Data Protection Regulation' for better flow.
The conjunction improves readability.
11.
LOWcopyedit
In Table 1 footnotes, ensure consistent capitalization for sentence fragments (e.g., 'Self-reported', 'Refers', 'The').
Capitalization inconsistencies are minor but should be standardized.
12.
LOWcopyedit
In Table 2 footnote b, improve punctuation by replacing the semicolon after 'blood draws' with a period or comma for clarity.
The current punctuation is awkward and could be clarified.
13.
LOWcopyedit
In Table 3 footnote a, ensure consistent spacing around commas and between graded terms and their definitions.
Inconsistent spacing is a minor formatting issue.
