Note: Mean (SE) are unadjusted values.

Note:

^‡95% CI for health education group (n=25) compared to mindfulness-based group (n=29) between-condition difference on change in outcome at six-weeks and six-months. Cohen’s d refers to the standardized effect size of the between-condition difference, and the p-value refers to the significance of the between-group condition effect. All between-condition effects are adjusted for the respective baseline level of each outcome, sex, and baseline age.

Note:

^*Refers to within-condition change from baseline of p<.05.
