Analyses include only participants with at least two measurements. Amount of change in clinical values over time differed significantly between program and comparison groups for the following outcomes after controlling for site, age, gender, study group, time of measurement, and interaction between study group and time: HbA1c values, Wald χ2(1) = 11.64, p < .001; good control of HbA1c, Wald χ2(1) = 11.39, p < .001; and good control of blood pressure, Wald χ2(1) = 5.54, p = .019.
