p-values for interaction were estimated using a log likelihood ratio test to compare models with and without cross-product interaction terms. p Interaction were derived by insomnia × characteristics in Models that adjusted for age, educational level, BMI (categorical), smoking status, drinking status, shift work, sleep duration (categorical), sleep drug, snore, hypertension, diabetes, dyslipidemia (except for the stratification variable in each subgroup)
