Note: Unmarked values = not significantly different from normal-weight class.
*Overweight and obese trajectory classes are significantly different from each other and from normal-weight class.
†Overweight and obese trajectory classes differ significantly from normal-weight class, but not from each other.
‡Cognitive impairment indicated by Short Portable Mental Status Questionnaire error score ≥4.
