Subclaims¶

q3 i? A linear mixed-effects model on per-minute depth accuracy found a highly significant Group×Minute interaction (β=+0.030 per minute, p<.001). → Yibo Meng 2026

q3 · i? · causal · r2

Minute-by-minute analysis of the 10-minute T2 phase with a linear mixed-effects model (Group, centred Minute, interaction, random intercept per participant). The printed "𝛽=+ 0.030per minute" is an unstandardised slope, so no standardised effect size is reported.

"The Group×Minute interaction was highly significant, 𝛽=+ 0.030per minute, 𝑝<. 001: the experimental group's accuracy rose roughly three percentage points per minute faster than the control group's"

Related Claims¶

• TibetCPR training produced depth-accuracy gains that substantially exceeded unguided practice and transferred to an unscaffolded post-test — a broader claim this one bears on
• The experimental group answered achievement tests faster (6.18 minutes) than the control group (7.51 minutes) — related
• In a randomised study with 40 CPR-naive lay adults in Tibet, 10 minutes of TibetCPR training produced rhythm-stabilisation gains that substantially exceeded unguided practice and transferred to an unscaffolded post-test — related
