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.
