T1 = study entry; T2 = end of study; SD = standard deviation; pT1 = level of significance between groups at T1; pT2 = level of significance between groups at T2; η2 = effect size: values of η2 = 0.01 were considered of small effect while η2 = 0.06 were defined as medium and η2 = 0.14 as large effect sizes.
