Among participants without VRF (A), RCS was adjusted for age, education, BMI, WC, depression, and testosterone. Among participants with one VRF (B) and two or more VRFs (C), RCS was adjusted for age, education, BMI, WC, hypertension, diabetes, CHDs, stroke, depression, and testosterone. The lines represent the MMSE score (solid lines) and 95% confidence intervals (shading). The reference values (y = 0, The y-axis is compressed) were set at the 10th percentile, and the knots were set at the 10th, 50th, and 90th percentiles of the level of estradiolBack to article page
