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 well-reported phase 3 RCT with a strong scientific premise, rigorous design, and transparent reporting. The main weaknesses are minor reporting gaps: no explicit CONSORT reference, no explicit statistical assumption checks, and no analysis code sharing. The copyedit pass found only minor typos and rounding inconsistencies.

Both reviewers agreed on all dimensions and study type (interventional). The statistics verification recomputed 5 tests, all consistent; coverage is limited to tests with test statistics/df or effect estimates with CIs. The citation check found no retracted or unresolved references. The integrity check flagged only low-severity rounding differences, which are not validity threats.

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

Efficacy claim is anchored to an adequate endpoint and a meaningful effect.

Recomputed 5 tests: 5 consistent, 0 inconsistent; 5 via agent-written checks.

4 integrity concerns flagged (0 high).

Reporting

Eight Dimensions8 pass

The introduction cites multiple studies on prevalence, co-occurrence, and consequences of prenatal anxiety, and notes the lack of preventive approaches. It also references the authors' own formative qualitative work that informed the intervention. The hypothesis follows logically from the cited evidence. Limitations of prior research (e.g., focus on depression, not anxiety) are explicitly addressed.

PASSReviewer 1· 90% conf

The paper establishes a strong scientific premise by citing prior research on prenatal anxiety as a predictor of postnatal CMDs, the treatment gap in LMICs, and the lack of preventive interventions, and it builds a logical rationale for the study.
