Model 1: Adjusted for age and age squared.

Model 2: Adjusted for age, age squared, marital status, education, smoking, alcohol consumption, physical activity index, BMI, sleep-disordered breathing, snoring.

Model 3: Adjusted for the same variables as in model 2, and depression score and anxiety score.
