Analysis of covariance of endline HbA1c of the intervention and control groups^{^a}

Group	HbA1c baseline (95% CI)	HbA1c endline (95% CI)	Estimated effect size (CI)	F	P-value
Intervention	6.84 (6.40 to 7.27)	6.26 (6.19 to 6.33)	−0.74 (−1.32 to −0.02)	12.92	0.015^{^b}
Control	6.36 (5.99 to 6.73)	6.82 (6.69 to 6.95)	−0.74 (−1.32 to −0.02)	12.92	0.015^{^b}

↵a Dependent variable: HbA1c endline. (HbA1c = glycosylated haemoglobin).
↵b The endline HbA1c was compared between the treatment groups adjusting for baseline HbA1c using ANCOVA.
