Subclaims¶

q2 i? In the LMM, post-to-delayed change was significant only at Centre 2 (Holm-adjusted p = 0.033), while Centre 1 remained above baseline at delayed follow-up. → Joshi U 2026

Joshi U, Sarkar A, Shukla A, Shrimali S, Bezbaruah NK, B Sanjay Kini, Baisil S, Sheth Z, Bhargava P, Shah S. (2026). Ears for examinations: a multicentre quasi-experimental evaluation of AI-generated revision podcasts on learning outcomes and retention among medical students.

q2 · i? · causal · r1

Primary linear mixed-effects model (TotalScore ~ Timepoint + Centre + Timepoint×Centre + (1|StudyID)) with Holm-adjusted planned contrasts; model-estimated means were 35.8 to 34.6 at Centre 1 versus 45.0 to 41.0 at Centre 2. No effect size printed for this contrast.

"Immediate pre–post gains were statistically clear in both centers (Holm-adjusted p < 0.001), while post–delayed change was significant only at Centre 2 (Holm-adjusted p = 0.033)."

Discussion¶

Learner Variables¶

• Long-Term Memory — outcome: instruction changes it

Related Claims¶

• AI-generated revision podcasts produce statistically significant immediate learning gains in medical students at both study centres — related
• Podcast gains extend beyond recall to higher-order application and analysis items at both centres — related
• Topic-wise gains were heterogeneous, with some topics showing no meaningful change — related
• Gains from an intensive period of second-language study persist for weeks without rehearsal. — a broader claim this one bears on
• Higher episode completion (>50%) is independently associated with greater learning gain, and the centre effect on gain is mediated by engagement — related
• Heterogeneous learning curves across practitioners create organizational challenges including perceived unfairness — related
• Exploratory pre-post questionnaire comparisons showed descriptively higher post-program means but no statistically significant differences after Holm adjustment — related
• VeriForge's integrated workflow is associated with higher one-week delayed recall of domain terms and a higher retention rate (exploratory) — related
