SD Standard deviation.

T0: Before intervention; T1: Two weeks after intervention; T2: First month after intervention; T3: Third month after intervention.

^aThe outcomes were based on two-way analysis of variance (ANOVA) of repeated measures.

^bThe outcomes were analyzed using an independent-samples t-test.
