Subclaims

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q3 i? Pooled RCT evidence shows no significant difference between VSs and mannequins or RPs on procedural skills (SMD=–0.12), with the required information size reached, implying a conclusive statistically insignificant result. → Jiang N 2024

q3 · i? · quant-synthesis · r3

Random-effects meta-analysis of 10 RCTs assessing procedural skills. Pooled SMD=–0.12 (95% CI –0.47 to 0.23) was not significant; TSA showed the RIS had been reached, implying a conclusive statistically insignificant result. Leave-one-out analysis was consistent.

"the pooled effect size did not reflect a significant difference between VSs and mannequins or RPs on the outcome of procedural skills (SMD=–0.12; 95% CI –0.47 to 0.23; I2=75%; P<.001)"
