Abbreviations: BOCF, baseline observation carried forward; CI, 95% confidence interval; CP, commercial programme; kg, kilogram; LOCF, last observation carried forward; MAR, missing at random; GLS, generalised least squares; SC, standard care; s.d., standard deviation.
P-value is given for the treatment difference.
a
completers are defined as those participants who provided a measured weight at 24 months.
b
completers are defined as those participants who provided either a measured or self-reported weight at 24 months.
