Subclaims¶

q3 i3 Against controls receiving no specific feedback, VBC showed significantly higher performance scores (SMD 1.58, p = 0.006) and change scores (SMD 1.26, p = 0.004). → Anderson Steven Mark 2025 q3 i2 Against controls receiving individualized feedback alone, VBC showed significantly higher scores (SMD 0.58, p = 0.004) and change scores (SMD 1.08, p < 0.0001). → Anderson Steven Mark 2025 q3 i? Against controls receiving supplementary material such as training videos or lecture slides, differences did not reach statistical significance. → Anderson Steven Mark 2025

q3 · i3 · quant-synthesis · r3

Subgroup analysis dividing control arms into three categories: no specific feedback; individualized feedback without video review; and supplementary material such as training videos or lecture slides. The largest advantage was against "controls who received no specific feedback", with effect sizes SMD 1.58 and SMD 1.26.

"Significantly higher mean performance scores (SMD 1.58, 95% CI 0.45, 2.70, and p = 0.006) and mean change scores (SMD 1.26, 95% CI 0.40, 2.11, and p = 0.004) were seen in the VBC compared to controls who received no specific feedback."
