Estimated mean differences in the ENHANCE Study physiologic outcomes between Technology Supported Behavioral Intervention (INT; n= 131) and Attention Control (n=132) participants at baseline, 3 and 6 months, based on random intercept models adjusted for A1c/eGFR status, age group and marital statusa

Random intercept model with fixed effects of time, treatment group, stratum, and interactions of fixed effects, adjusting for age group and marital status. Statistical significance of main effects and treatment by time interaction assess using Wald statistic. Mean differences (INT-Control) at 3 and 6 months were estimated using linear contrasts.
