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 i3 A random-effects meta-analysis of three cross-sectional studies found a positive pooled correlation (r = 0.67, 95% CI 0.22 to 0.88) between robotic VR simulator performance and intraoperative performance, with substantial heterogeneity. → Schmidt MW 2021

Meta-analysis of three cross-sectional predictability studies (59 participants total) pooling correlation coefficients via Fisher's z-transformation with inverse-variance weighting. The pooled correlation was "r = 0.67, 95 per cent c.i. 0.22 to 0.88", with substantial heterogeneity between studies.
"Random-effects meta-analysis based on Fisher’s z-transformation of correlation coefficients revealed a positive pooled correlation (r = 0.67, 95 per cent c.i. 0.22 to 0.88) between robotic VR simulator performance (combined over all tasks assessed) and intraoperative performance"
Discussion¶
Related Claims¶
- Correlations between simulator task performance and intraoperative GEARS domains vary by task, and one study found no correlation between dVSS scores and intraoperative GEARS scores — a narrower finding that bears on this claim
- Virtual reality simulator performance has limited correlation with intraoperative robotic hysterectomy performance. — reports the opposite
- Hung et al. found a high correlation between GEARS scores for a simulated robotic partial nephrectomy and GEARS scores for the procedure on a live porcine model — a narrower finding that bears on this claim
