Forest plot of the associations between menopause and cognitive test scores for CERAD trial 1, CERAD trial total, and CERAD delayed recall. Early menopause was used as the reference group. There existed a positive correlation between the age at menopause and cognitive function. A later onset of menopause is associated with higher cognitive scores in CERAD trial 1, CERAD trial total, and CERAD delayed recall. Delayed menopause exhibited the most robust positive correlation with cognitive function, with statistical significance consistently observed across model 1 and model 2, and model 3. Model 1: no adjusted; Model 2: adjusted for age; Model 3: were adjusted for age, BMI, alcohol intake, smoking, PIR, education, race/ethnicity, hypertension, and diabetes
