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.
q2 i? Studies reporting high minimal training duration (>30 h) concentrated in a shorter period found a reduction in complication rates, whereas spaced-out sessions spread over more than 6 months did not. → Dormegny Lea 2024

q2 · i? · review · r2
Review-level moderator analysis of training schedule across included studies: spaced-out simulator sessions spread over more than 6 months did not significantly reduce complication rates, while concentrated programs of more than 30 h over several weeks did.
"Considering the entire surgical procedure, spaced-out sessions on a virtual reality simulator (i.e., spread over more than 6 months [20, 21]) did not significantly reduce complication rates, while studies reporting high minimal training duration (> 30 h) concentrated in a shorter period of time (several weeks) did find such a reduction [24, 26, 29]."
