Body Weight Change
时间窗: 16 weeks
Body weight (in gown, without shoes) was measured at each clinic visit on a medical quality digital scale (Health-o-meter 349KLX, Pelstar, McCook, IL) following a 10-14-hr fast. The relevant time points to determine body weight change were baseline and 16 weeks. The value for body weight at 16 weeks minus the value at baseline was the calculation used to determine body weight change.
