Statistics were not checked: no recomputable values were found in this text — no test statistic reported with its degrees of freedom, no effect estimate printed with both a 95% CI and a p-value, and no percentage printed with both its count and its denominator.

Problems surfaced2 types

Overstated conclusions2

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.

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 is a well-conducted and transparently reported randomised controlled trial. The design is rigorous, with appropriate randomisation, blinding of the statistician, sample size calculation, and comprehensive reporting of demographics, ethics, resources, statistics, and data/code availability. Minor reporting gaps include lack of explicit CONSORT adherence and a few copyedit issues.

This is a post-publication audit of a published RCT. Both reviewers independently scored all eight dimensions and agreed on all statuses. The statistics verification component checked 0 tests (none recomputable), so no statistical errors were found, but this does not confirm correctness of unreported tests. The citation check found no retracted or unresolved references. The reproducibility check confirmed the data link is live.

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

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

Reporting

Eight Dimensions8 pass

The introduction cites prior work and identifies gaps: 'Internationally, clinical guidelines offer conflicting recommendations on the use of knee bracing for knee osteoarthritis, and evidence from high quality randomised controlled trials is sparse.' The rationale links this to the trial's objective. Limitations of prior research are addressed in the discussion, noting previous trials were 'hampered by targeting only one knee compartment for all participants, small sample sizes, risk of bias, lack of follow-up beyond three months, and heterogeneity.'

The paper establishes a clear scientific premise, citing conflicting guidelines and sparse high-quality RCT evidence, and provides a logical rationale for the trial.
