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.

This perspective article on sialic acids in Leishmania biology demonstrates strong reporting of its scientific premise (extensive citation, clear rationale, acknowledged limitations) and adequate reporting transparency (limitations, proportional conclusions, funding/COI). As a narrative review, most rigor-related dimensions (study design, biological variables, ethics, key resources, statistics, data/code) are not applicable because the paper does not present new experimental data.

All three independent reviewers converged fully: the paper was classified as a narrative review/perspective, and six of eight dimensions were judged not applicable. Only scientific premise and reporting transparency were scored, both passing. The minor divergence on methods completeness (reviewer 3 marked 'reported but inadequate') was carried forward. The copyedit pass identified 15 issues (1 major). The citation check found 2 references not found in registries; no retractions. No statistics were re-computable (0 tests). The claim audit found no under-evidenced claims.

12 major claims checked against the paper's own evidence: all adequately supported.

The paper cites extensive prior research on glycoconjugates in Leishmania (sections 1-3) and acknowledges strengths and weaknesses. It links the premise (sialic acids understudied) to the objectives, and in section 7 discusses specific limitations of available reagents (lectins, lability of O-acetylation). All three sub-criteria are met.

Per reviewer (3) — the votes behind the verdict

PASSReviewer 1· 95% conf

The paper establishes a clear scientific foundation by reviewing prior work on Leishmania glycobiology, providing a rationale for studying sialic acids, and explicitly discussing limitations of current probes and methods.

Evidence

direct quote[Abstract]

“Parasite-specific glycoconjugates have served as important determinants influencing parasite recognition, internalization, differentiation, multiplication, and virulence.”

direct quote[Abstract]

“Despite the steady progress in the field of parasite glycobiology, sialobiology has been a less traversed domain of research in leishmaniasis.”

direct quote[Section 7, paragraph 6]

“there are a few limitations in this field of work due to lack of reagents/probes.”

PASSReviewer 2· 95% conf

The premise that sialic acids are important determinants in Leishmania biology is well established through extensive citation of prior work and a clear rationale for the review.

Evidence

“Hence, this review has made a modest attempt to assemble the observations on the sialobiology of Leishmania sp. highlighting their importance in leishmaniasis.”

direct quote[Section 7, penultimate paragraph]

“Although we have provided strong evidence in support of the presence of 9-O-AcSA and linkage specific SA, there are a few limitations in this field of work due to lack of reagents/probes.”

PASSReviewer 3· 90% conf

The paper establishes a clear scientific foundation by citing prior research on Leishmania glycobiology and sialic acids, providing a logical rationale for the review's focus, and acknowledging limitations in the field.

Αlpha¹ Rigor Action ItemsFinal pass before journal submission

Published paper is robust as a narrative review: the premise is well-supported, limitations are acknowledged, and conclusions are appropriately tempered. An informed reader should weigh the lack of a stated search strategy or reporting guideline — this reduces transparency on how studies were selected. The two references not found in any registry warrant verification. The high number of copyedit typos/formatting errors (15 issues, 1 major) suggests the paper would benefit from a careful proofreading pass for a correction.

1.
HIGHreporting
Section 1 or Methods: Add a statement clarifying the review type (narrative vs. systematic) and — if a systematic approach was used — state the literature search strategy (databases, search terms, inclusion/exclusion criteria) or clearly state that this is a non-systematic narrative review.
A narrative review without a stated search strategy may leave readers uncertain about how studies were selected, reducing transparency.
2.
HIGHreporting
Add a statement referencing a reporting guideline (e.g., the 'Scale for the Assessment of Narrative Review Articles' (SANRA) or a similar framework) in the Introduction or Methods section.
Reporting guidelines improve completeness and allow readers to assess review quality; currently none is mentioned.
3.
HIGHreporting
Verify the two references not found in any registry (titles: 'Current status and perspectives of the immunotherapy of leishmaniasis' and 'Control of the leishmaniases') — correct the citations or add missing details so they can be located.
References that cannot be found in any bibliographic registry may be fabricated or have citation errors; they must be corrected or removed.
4.
HIGHcopyedit
Author line: Correct the jumbled author names 'Ghoshal Angana Mandal Chitra' to 'Angana Ghoshal and Chitra Mandal'.
Correct author attribution is essential for credit and indexing; the current rendering is uninterpretable.
5.
HIGHcopyedit
Section 7, Table 1: Clarify units consistently (μg/2×10^9 cells vs μg/5×10^9 cells) by using separate rows or a clear footnote explaining the different cell counts per strain.
Inconsistent units in the table may confuse readers and obscure quantitative comparisons between strains.
6.
HIGHcopyedit
Section 7, Table 1 footnote: Define 'ND' explicitly in the table footnote (it is used in the table but defined only in the body text as 'not detectable').
Table footnotes should be self-contained; undefined abbreviations reduce readability.
7.
MEDIUMcopyedit
Throughout: Standardize the abbreviation for 9-O-acetylated sialic acid to '9-O-acetylated sialic acid (9-O-AcSA)' at first use, then '9-O-AcSA' consistently (currently also appears as '9- O -AcSA' with spaces).
Inconsistent formatting of technical abbreviations may confuse readers and reduces professional polish.
8.
MEDIUMcopyedit
Figure 1 legend: Change 'Graph-Pad Prism statistics software (Graph-Pad Software Inc., San Diego, CA, USA)' to 'GraphPad Prism (GraphPad Software, Inc., San Diego, CA)' — the standard name of the software.
Inconsistent naming of a well-known software package appears unprofessional and may hinder reproducibility.
9.
MEDIUMcopyedit
Abstract: Remove extra space before period in 'Leishmania sp .' to read 'Leishmania sp.'.
Typographic errors in the abstract create a poor first impression for readers and editors.
10.
MEDIUMcopyedit
Section 7, text: Remove stranded punctuation in '([–], ).' to read '([–]).'.
Misplaced punctuation and brackets are distracting and suggest careless formatting.
11.
MEDIUMcopyedit
Section 10: Correct typo 'consequencess' to 'consequences' (two occurrences).
Repeated typos undermine the authority of the review's concluding section.
12.
MEDIUMcopyedit
Section 7, HPLC data: Correct 'Ne5Gc' to 'Neu5Gc' for consistency with Tables and rest of text.
Inconsistent chemical nomenclature may cause confusion about which sialic acid species is being reported.
13.
MEDIUMcopyedit
Section 7, last paragraph: Fix the stray parentheses in 'similar finding ().' by removing the parentheses or adding a space and citation.
Errant punctuation hinders readability and looks unprofessional.
14.
MEDIUMcopyedit
Table 2: Add a note for L. amazonensis (LV81) explaining that only Neu5Ac is reported (no Neu5Gc) while Table 1 notes a 'trace amount' of Neu5Gc for this strain.
Inconsistency between tables for the same strain may confuse readers and should be explained.
15.
MEDIUMreporting
Consider adding a comprehensive summary table of all Leishmania strains discussed, with their sialic acid profiles and clinical relevance for easier reference.
A summary table would help readers quickly compare strains across the multiple studies cited.
