Generalized Estimating Equations (GEE) were applied for pre- to post-intervention and inter-group comparisons. When the Wald χ2 was significant, a Fisher post hoc test was employed to identify the mean differences. The ES was calculated as the post-training mean minus pre-training mean divided by the pooled standard deviation [
