At baseline and 2 weeks, there were no significant differences between DTSQs total scores in the three study arms ( P = 0.283 and P = 0.789) or between the two intervention arms ( P = 0.602 and P = 0.964), but at 16 weeks, the differences were highly significant ( P = 0.009 and P = 0.002).
When we included the baseline HbA 1c values in a regression model, the difference in change in HbA 1c between the three groups was borderline significant ( P = 0.056), but the relative differences between groups altered to a −0.6% (−1.2 to 0.1; P = 0.082) change in HbA 1c in the CarbCount arm and a −0.8% (−1.4 to −0.1; P = 0.017) change in HbA 1c in the CarbCountABC arm compared with the Control arm (reference group).
