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? In cholecystectomy, feedback led to a reduction in procedure time (p=0.022) and an improvement in economy of movement (p<0.001). → Trehan Abhishek 2015

q3 · i? · review · r3
RCT by Grantcharov et al in live cholecystectomy with 16 surgeons, two per surgeon, feedback arm versus no-feedback control arm. Table 3 reports procedure time p=0.022 and economy of movement p<0.001 for improvement in the feedback group compared to control.
"In cholecystectomy, feedback led to a reduction in procedure time (p=0.022) and an improvement in economy of movement (p<0.001)."
