Arm-based network meta-analysis comparing the effect on weight loss, FBG, and diabetes incidence between intervention and control arms, by intervention strategy

Comparison	Weight* (kg)		FBG† (mmol/L)		Diabetes incidence‡
	n	Change [95% CI]	n	Change [95% CI]	n	OR [95% CI]
Group education by COM vs. control	26	−2.1 [–3.1, −1.0]	9	−0.04 [–0.17, 0.10]	4	0.71 [0.37, 1.35]
Group education by HP vs. control	30	−1.1 [–2.3, 0.1]	22	−0.09 [–0.19, 0.01]	11	0.67 [0.49, 0.92]
Individual counseling by HP vs. control	3	−0.3 [–3.0, 2.4]	2	−0.19 [–0.43, 0.04]	1	0.71 [0.37, 1.36]
Education/counseling by TEC vs. control	8	−0.14 [–2.8, 2.5]	1	−0.08 [–0.40, 0.23]	1	0.21 [0.1, 4.27]

This was a multiple treatment comparison meta-analysis where arms across studies were grouped according to the intervention employed, and a pooled effect for each group, compared with control arms, was estimated. n = number of intervention arms. Mean (SD) duration of active intervention: 23 (22) weeks; range 1–130. Average (SD) number of sessions offered: 18 (25); range 1–58. COM, community member; HP, health care professional; TEC, technology.

*61 studies including 67 interventions arms and 25 control arms.

†29 studies including 34 interventions arms and 17 control arms.

‡14 studies including 17 interventions arms and 7 control arms.
