Based on ANCOVAs with the change score from baseline to the 3 month assessment as the dependent variable adjusting for the baseline value of the dependent variables, age, and baseline understanding of diabetes self-management. Unadjusted means are presented in the table. Intent-to-treat analysis with missing data imputed by baseline observation carried forward.
