Problems surfaced6 types

Numerical inconsistencies1

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

Overstated conclusions3

Conclusions that reach past what the paper's own results support — including a significance claim that no longer holds when the statistic is recomputed, and efficacy resting on an unvalidated surrogate endpoint.

Efficacy rests on an unvalidated surrogate endpointAssessed
Treatment effect not shown to be clinically meaningfulAssessed
Conclusions only partially backed by the presented evidenceAssessed

Data authenticity concerns1

An adversarial read for patterns associated with data that may not be genuine: results that look too clean, implausibly large effects, duplicated data or images, and methods that do not match the results reported.

Other integrity concernAssessed

Reporting gaps1

Required detail the manuscript never states — study design, biological variables, ethics approval and consent, key resources, statistical reporting, data and code availability, and overall transparency.

Ethics/consent reporting incompleteAssessed

This Αlpha¹ Rigor Review uses AI 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.

A well-conducted and well-reported RCT of LLM assistance for general cardiologists, with minor reporting gaps (sex not reported, no named IRB, no power analysis, code repository not linked).

Both reviewers classified the study as interventional (RCT). The design is a randomized controlled trial with blinded evaluation. The main divergence between reviewers was on biological variables (Reviewer 1 pass, Reviewer 2 warn due to missing sex) and on key resources (Reviewer 1 pass, Reviewer 2 pass with a note on the Python version typo). The synthesized statuses reflect the more conservative reading where a reporting gap exists.

9 major claims checked against the paper's own evidence: 1 only partially supported (evidence backs part of the claim; gaps or caveats remain); the rest adequately supported.

Premise concern: surrogate not validated for clinical benefit; effect size not shown to be clinically meaningful.

Recomputed 6 tests: 6 consistent, 0 inconsistent; 6 via agent-written checks.

4 integrity concerns flagged (0 high).

Eight Dimensions7 pass · 1 warn

The introduction cites WHO workforce shortages, HCM prevalence, and prior LLM studies, acknowledging the lack of RCTs and real-world data. The rationale for using genetic cardiomyopathies as an indicative example is logical. Limitations of prior work (e.g., simulated data, text-only) are explicitly addressed by using real-world multimodal data.

PASSReviewer 1· 90% conf

The paper establishes a clear premise: scarcity of subspecialist expertise, and prior work on LLMs in medicine is cited, with gaps identified.

Evidence

“Despite more than 500 observational LLM papers published in 2024, systematic reviews of LLMs in medicine have consistently shown a lack of RCTs”
