Sensitivity Analyses
weight loss
Only one variable, education, met the conditions for performing MICE to impute missing data (between 5% and 25% missing data). The observed results using 11 imputed datasets were comparable to the primary analysis, and no associations were identified (online suppl. Table S3).In the sensitivity analysis using only study-measured weight at the 5-year follow-up (online suppl. Table S1), being older at baseline remained associated with lower weight regain or greater weight loss, but the effect size was smaller (coefficient −0.092 (95% CI: −0.15, −0.04), The final sensitivity analysis was of all independent variables included in a single model, which also adjusted for the intervention group, baseline weight, weight change between baseline and 1-year, research centre, and source of the 5-year weight data (full results available in online suppl. Table S4). In this model, older age at baseline remained associated with lower weight regain or greater weight loss (coefficient −0.15 (95% CI: −0.25, −0.04),
