For categorical variables, values are frequency (%). For continuous variables, values are mean ± SD if normally distributed and median (IQR) if skewed. HDL-C, HDL cholesterol; LDL-C, LDL cholesterol.
2
Among the completers (n = 148), 1 participant developed hypothyroidism and was an a priori exclusion from analyses of all outcome variables in this report.
3
Lipoprotein(a) was missing for 1 participant at pre-weight-loss.
