Statistical analysis
Assuming that an expected mean composite score would be 48 out of 60 in the control group, using a standard deviation of 6 points out of 60, and considering that an improvement of one standard deviation (difference accepted for studies in education [The composite score was compared immediately after training between the two groups (i.e., OT+ versus OT-). Secondary outcomes were analyzed by comparing the two groups immediately after training and 1 month after training.Results are presented as mean ± standard deviation or percentage. Statistical analysis was carried out with JMP® software (Cary, NC 27513–2414, USA). Statistical comparisons used two-tailed Student’s t-test and analysis of variance for parametric and continuous variables, a Chi-square test for proportions, and a Wilcoxon test for non-parametric variables. A value of
