In a nonrandomized Chinese study with 481 university students completing follow-up, adding a CPR/AED game-based mobile app to traditional training produced higher 7-day theoretical and practical-skill scores and a 6-month median knowledge score of 9/10 versus 8/10 for traditional training alone.
What this does not establish
Knowledge retention is not retained hands-on competence, real emergency behavior, patient survival or a randomized causal estimate.
Counterevidence & uncertainty
Nonrandom allocation, no preintervention survey for some outcomes and a young highly educated sample limit causal strength and generalizability.
What would change the reading
Update with randomized trials measuring long-term practical competence and real or validated simulated response.
