Data are presented as mean ± SD. Work, occupation, and stress were adjusted. Bonferroni correction with adjusted α-level (α′ = 0.05/3 = 0.0167) was used for multiple comparisons between each time point and the baseline. No difference between a time point and the baseline was found.
*Significantly different between two groups, P < .05.
