By treatment analysis: difference in obesity and metabolic characteristics between those maintaining participation (≥6 sessions attended) in the lifestyle counselling versus those not maintaining participation within the intervention group.

BMI = Body mass index, HbA1c = haemoglobin A1c, HDL = high-density lipoprotein, LDL = low-density lipoprotein, 95%CI = 95% confidence interval. aMaintenance is defined as having attended 6 sessions or more for lifestyle counselling (on top of an initial intake visit). bThe differences with corresponding 95%CI's in changes of metabolic characteristics over time between those maintaining and not maintaining participation in the lifestyle counselling, determined with independent sample t-tests for continuous measures and chi-square tests for categorical measures. cP<0.05 for differences between baseline and follow-up measurements of metabolic characteristics determined with paired t-test.
