Table 7. Linear regression analysis for association between the weekend catch-up sleep duration and the triglyceride/high-density lipoprotein cholesterol ratio, stratified by the weekday sleep duration.

ß coefficients; CI, confidence interval; TG/HDL, triglyceride/high-density lipoprotein cholesterol ratio; WCUS, weekend catch-up sleep; h, hours.

Adjusted for age, sex, body mass index, household income, education, smoking, drinking, physical activity, diabetes, hypertension, statin use, total sleep duration, TG/HDL ratio into quintiles.
