It is noteworthy that BMI category changes were more represented in retrospective studies than in prospective studies (26% [95%CI, 14%–41%] vs 9% [95%CI, 2%–19%]; P = 0.047) (see Figure S5A in the Supporting Information online) and in trials with a follow-up duration of more than 2 years, although in this case the difference did not reach statistical significance (28% [95%CI, 14%–43%] vs 11% [95%CI, 3%–21%], P = 0.06) (see Figure S5B in the Supporting Information online).
