Fig. 2From: Effect of changes in sleeping behavior on skeletal muscle and fat mass: a retrospective cohort studyAdjusted means of change in fat mass index according to change in sleep duration (reduction, maintenance, or extension) and quality (good or poor at baseline periods and good or poor at follow-up periods). Adjusted means (95% CI) of change in predicted fat mass index (pFI). Adjusted means were calculated using linear regression analysis after adjusting for the sleeping duration at baseline, age, sex, income level, history of depression, calorie intake, protein intake, fat intake, body mass index, follow-up duration, drinking status, smoking status, and physical activity. *p-value < 0.05Back to article page
