Correlation between Body Mass Index and Cognitive Function in Patients with Atrial Fibrillation

Figure 2

Association between BMI and cognitive function of atrial fibrillation. A threshold and a non-linear relationship between BMI and MoCA score were found in a generalized additive model. The solid red line represents the smooth curve fit between variables. Blue bands represent the 95% confidence interval from the fit. Models were adjusted for age, sex, smoking or not, alcohol consumption, marital status, degree of education, living condition, aspirin, warfarin, history of myocardial infarction, cerebral infarction history, diabetes mellitus, hypertension, valvular disease, hyperlipidemia, coronary artery disease, heart failure, SBP, DBP, D-dimer, creatinine, FT4, FT3, left atrial diameter.
