q4 i3 Real clinical interactions (SMD = 1.74), simulated clinical interactions (SMD = 1.06) and virtual environment learning (SMD = 0.93) each showed significant positive effects. → Pang Xuefei 2026

q4 · i3 · quant-synthesis · r2

Subgroup analysis by ECE type in the meta-analysis. All three modalities were significant; the real-clinical-settings estimate had the widest interval and highest heterogeneity (I² = 98.3%).

"significant benefits were found for exposure to real clinical settings (SMD = 1.74, 95% CI = 0.83-2.66, I² = 98.3%, P < .001), simulated clinical interactions (SMD = 1.06, 95% CI = 0.46-1.67, I² = 96.0%, P < .001), and virtual environment learning (SMD = 0.93, 95% CI = 0.29-1.58, I² = 88.2%, P < .001)"
