| Education: college and above, N (%) | 120 (49.4) | 2054 (57.0) | 0.023 |
| Hypertension, N (%) | 108 (44.4) | 1444 (40.1) | 0.20 |

| Stroke, N (%) | 16 (6.6) | 143 (4.0) | 0.06 |
| Fasting glucose (mg/dL), mean (SD) | 107.3 (25.6) | 104.6 (22.7) | 0.13 |
| Baseline 3MSE, mean (SD) | 92.8 (5.4) | 94.4 (4.6) | <0.001 |
| Weekly tea drinker, N (%) | 65 (26.7) | 887 (24.6) | 0.39 |
| Daily tea drinker, N (%) | 35 (14.4) | 443 (12.3) | |
| Weekly coffee drinker, N (%) | 50 (20.6) | 707 (19.6) | 0.11 |
| Daily coffee drinker, N (%) | 133 (54.7) | 2185 (60.7) | |
| Follow-up variable | |||
| 3MSE, mean (SD) | 73.5 (11.7) | 93.1 (5.0) | <0.001 |
Fast cognitive decline was defined as decline of 3MSE score ≥12 points.
P values were calculated using Fisher’s exact test (2-sided) for binary variables, Pearson chi-square test for categorical variables and Mann Whitney U test for continuous variables.
