Figure 6. Clinically relevant changes in pain intensity among yoga and control group participants.

Figure 6

Mean percent of the total participants who reported a clinically important improvement (18.5 mm change) in pain intensity is depicted. Hägg et al. {Hägg, 2003} using the external criterion of patient global assessment of treatment effect, determined that 18–19 units on a 100 millimeter VAS was a minimally clinically important difference. Statistically significant p values from follow-up linear contrasts at 12 and 24 weeks to the repeated measures ANOVA test are indicated as follows: * p<.05, ** p <.01, *** p <.001.
