The joint association between long sleep duration and AD-GRS for AD risk. A: The interaction between sleep duration and AD-GRS. B: Participants who had a low AD-GRS with normal sleep duration were used as the reference (Re). C: Participants who had an intermediate AD-GRS with long sleep duration were used as the reference (Re). The multivariable model was adjusted for age, gender, ethnicity, TDI, education level, smoking, alcohol use, hypertension, stroke, myocardial infarction, and diabetes. The vertical line indicates the reference value of 1. AD-GRS stands for Alzheimer's disease genetic risk score
