Using health economic modelling to inform the design and development of an intervention: estimating the justifiable cost of weight loss maintenance in the UK

Table 1 Weight regain per annum: estimates from random-effects meta-analysis

	Weight maintenance intervention (n = 661)			Control (no intervention) (n = 383)			Difference between groups
Year	N	Mean	95% CI^a	N	Mean	95% CI^a	N	Mean	95% CI
0	14	−8.93	(−9.49, − 8.36)	14	− 8.93	(− 9.49, − 8.36)
1	15	1.33	(0.67, 1.99)	15	2.84	(2.01, 3.67)	15	−1.38	(−2.2, −0.55)
2	2	4.38	(3.64, 5.11)	2	5.6	(5.19, 6.02)	2	−1.23	(−1.96, −0.49)

N indicates total number of intervention arms; CI: Confidence intervals; estimates are in kg; ^a95% CI of mean weight change. The weight for year 0 is the weight loss before weight maintenance intervention begins and the weight in year 1 and 2 is the weight regain per annum during weight maintenance intervention
