- Model 1 included age, sex, BMI, APOE ε4, smoking status, education, use of anxiolytic or antidepressants, antihypertensive drugs, statins, and other lipid-lowering medication and MMSE score; Model 2 included ATN status plus the conventional risk factors included in Model 1; Model 3 included the ATN-related sncRNA signature plus the conventional risk factors included in Model 2; Model 4 included the ATN-related sncRNA signature plus the conventional risk factors included in Model 2 and ATN status. Exposure contrast is per z-score increase in the sncRNA signature. *P value < 0.05, **P value < 0.01, ***P value < 0.001
