*The risk in the intervention group (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI).
†OIS not met.
BMI, body mass index; CI, confidence interval; FPG, fasting plasma glucose; MD, mean difference; RCT, randomised controlled trial.
