Annual slope of weight change was determined for each individual using ordinary least squares regression with first 2 years of weight data to minimize the effect of survival on category of weight change. Weight change slope, total weight change and total study follow-up time are reported as median (IQR). Otherwise, results are presented as mean (SD) or percentages.
