a
Adjusted for age, clinic site, race, education, smoking status, alcohol intake, depression, sleep onset insomnia, sleep maintenance insomnia, diabetes, hypertension, physical activity, self-rated health and medication use.
b
Analysis stratified according to length of follow-up, with adjustment for covariates in the fully adjusted model.
c
Sensitivity analysis further adjusted for anxiety, cognitive function and excessive daytime sleepiness, in addition to covariates in the fully adjusted model.
