CS control site, IS intervention site, cm centimetres, BMI body mass index, WC waist circumference, SBP systolic blood pressure, DBP diastolic blood pressure
The findings in this table are presented for participants who completed the follow-up assessments only
^a P-values demonstrate the statistically significant difference in change at follow-up within the IS and CS
^b P-values demonstrate the statistically significant difference in change at follow-up between the IS and CS (except for job type, age, height where P-value demonstrates difference between sites pre-intervention)
