q3 i2 After excluding Cai et al. and Yang et al., the clinical analysis skills effect size decreased to Cohen's d = 0.50 (95% CI: 0.38 to 0.62) with I2 = 1.4%, though statistical significance was retained. → Shi Xu-Ying 2025

q3 · i2 · quant-synthesis · r2

Sensitivity analysis sequentially excluding each study to evaluate robustness of the combined effect size. Excluding Cai et al. and Yang et al. reduced heterogeneity dramatically and lowered the effect size, though significance was retained.

"After excluding these two studies, the I2 statistic for the combined Cohen’s d decreased to 1.4%, and the heterogeneity p-value increased to 0.419. The revised combined effect size was Cohen’s d = 0.50 (95% CI: 0.38 to 0.62, P < 0.001), which did not alter the outcome of the original analysis."
