Results are presented as β (95%CI) and P values from survey-weighted linear regression. β represents the change in sleep duration (hours) per 1-unit increase in the original, unstandardized triglyceride-glucose – a body shape index. Model 1 was unadjusted; model 2 was adjusted for age, sex, and race; model 3 was further adjusted for socioeconomic, lifestyle, blood pressure, laboratory, and cardiovascular covariates. In subgroup analyses, the corresponding stratification variable was not included in the model. Ref: Reference.
