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 i3 In a cross-sectional study of 28 surgeons using a modified dV-Trainer, total GEARS scores for VR renorrhaphy correlated highly with GEARS scores for robotic partial nephrectomy on a live porcine model (r = 0.8, p < 0.0001), as did all GEARS subdomains (r = 0.7–0.9). → Schmidt MW 2021

Cross-sectional study (Table 4) of 28 expert and intermediate surgeons assessed on a modified dV-Trainer renorrhaphy task followed by robotic partial nephrectomy on a live porcine model. The article reports a "high correlation" with r = 0.8 (p < 0.0001) for total GEARS and r = 0.7–0.9 for subdomains.
"Hung and co-workers36 reported a high correlation between the total GEARS scores for the robotic VR simulated task and the total GEARS score of a robotic-assisted partial nephrectomy in a live porcine model (r = 0.8, p < 0.0001), as well as between all GEARS subdomains (r = 0.7–0.9, P < 0.001)"
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 — related
- Robotic VR simulator performance is positively correlated with intraoperative performance, with a pooled correlation of r = 0.67 (95% CI 0.22 to 0.88) — a broader claim this one bears on
