By treatment analysis: difference in obesity and metabolic characteristics between those attending the lifestyle counselling (≥2 sessions attended) and those not attending within the intervention group.

BMI = Body mass index, HbA1c = haemoglobin A1c, HDL = high-density lipoprotein, LDL = low-density lipoprotein, N/A = not applicable, SD = standard deviation, 95%CI = 95% confidence interval. aAttendance is defined as having had two or more sessions of 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 attending and not attending the lifestyle counselling were 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-tests.
