M, means; SD, standard deviations; T, time. ^ap_adj < 0.01; compared to T0, ^bp_adj < 0.01; compared to T1, ^cp_adj < 0.01; compared to T2, ^*Normality test significant. For mixed linear models with a main effect of time, post-hoc pairwise comparisons of dependent variable means were carried out between subsequent time points, adjusting for multiple comparison using Bonferroni corrections.
