¹Values are mean changes between week 1 (percentage of weight change and body weight) or 2 (all other measures) and week 14 (95% CIs). LOCF and completers anaylsis presented. *,**Different from SW, *P < 0.05; **P < 0.01. LOCF, last observation carried forward; SC, standard care; SW, Slimming World.

²Analyses controlled for method of assessing body composition (BodPod or bioelectrical impedance).
