Notes: Baseline assessment was obtained prior to the start of the intervention. Post-intervention assessment was obtained 2 months from the start of the intervention. Follow-up assessment was 6 months from the start of the intervention. Adjusted mean differences are (tMBSR – tSupport). The statistical test for assessing between group differences tests the coefficient for the group indicator variable in a multiple regression model adjusted for baseline value, and design strata variables - dialysis (yes/no), diabetes (yes/no). Paired t-tests were used for comparing mean changes from baseline to post-intervention or baseline to follow-up within a single group.

^aHigher scores indicate more symptoms

^bSF-12 scores are standardized to the general US adult population (mean=50, SD =10), and higher scores indicate better health states, less pain.
