Sex difference in association of HGS with incident MCI in overall and ≥ 50 years group. The estimated OR of median HGS in male and female was set as the reference (OR = 1), and the logistic regression model was used to fit the change of ORs (95% CI) with the increase of HGS. The model was adjusted for age, baseline MOCA-BC score, ethnicity, education, income, BMI, smoking, drinking, physical labor level, hypertension, diabetes, dyslipidemia and coronary heart disease. OR Odds ratio, CI Confidence interval, MCI Mild cognitive impairment, HGS Handgrip strength
