Subclaims¶

q3 i3 The experimental group's pre-to-post gain in the proportion of compressions within the 50–60 mm range was substantially larger than the control change (Cohen's d = 3.66). → Yibo Meng 2026

Yibo Meng, Ruiqi Chen, Zhiming Liu, and Xiaolan Ding. (2026). TibetCPR: A Multimodal Tactile Feedback System to Enhance Cardiopulmonary Resuscitation Training in High-Altitude Regions of Tibet. arXiv. https://arxiv.org/abs/2606.07765 doi:10.48550/arxiv.2606.07765

q3 · i3 · causal · r2

Randomised controlled study with 40 participants; depth accuracy was the proportion of compressions in the 50–60 mm guideline range. Experimental accuracy rose from M=0.277 to M=0.558 while control was essentially unchanged; ANCOVA gave F(1,37)=203.17, partial η²=.846.

"A direct between-group comparison of the change scores ( Δ=𝑇 3−𝑇 1) confirmed that the experimental gain was substantially larger than the control change,𝑡( 38)= 11.56,𝑝<. 001, Cohen's 𝑑= 3.66"

Discussion¶

Related Claims¶

• In one experiment with 256 undergraduates, computer-based lesson versions that included practice produced significantly higher posttest scores than versions without practice — the general claim this finding bears on, with the studies behind it
• 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
• Depth accuracy rose progressively during the intervention, with the experimental group improving roughly three percentage points per minute faster than the control group — a narrower finding that bears on this claim
