p-value between both study groups after 6 months of follow up 1. Two-way ANOVA was used to find the p-values (Post-hoc analysis using the Games-Howell procedure). The t-statistic is further from zero than the critical values considered to reject the Null Hypothesis. C.I, confidence interval (group statistics); SD, standard deviation; df, degrees of freedom. The effect size was measured by Partial Eta Squared (η²). According to Cohen’s classification of effect size, if 0.01 ≤ η² ≤ 0.06 = small, if 0.06 ≤ η² ≤ 0.14 = medium, η² ≥ 0.14 = large.
