Subclaims¶

q3 i? Berges et al. found a weak and negative correlation between overall intraoperative performance and overall simulation performance. → Arcamo K 2025 q3 i? The review concludes that virtual reality simulator performance has limited correlation or validity in predicting intraoperative performance. → Arcamo K 2025 (2)

The review synthesizes that "there was an overall weak and negative correlation between intraoperative and simulation performance," suggesting better intraoperative scores correlate with worse simulation performance.

"Indeed, there was an overall weak and negative correlation between intraoperative and simulation performance, suggesting that better intraoperative GEARS scores correlate with worse simulation performance."
