Box plot representing the SCL-90-R subscale scores of the yoga-training group before (Pre) and after (Post) 12 weeks of yoga training (n = 21). The 25th and 75th percentiles are represented by the lower and upper borders of the grey box. The dark line within the grey box represents the median. The whisker error bars represent the 10th and 90th percentiles. (A-D) Scores for somatization (p = 0.006), depression (p = 0.002), anxiety (p = 0.002), and hostility (p = 0.007) from SCL-90-R were significantly decreased after 12 weeks of yoga training compared with those before starting yoga training. Statistically significant differences are shown: **P < 0.01.
