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.
