Demographics characteristics for participants assessed at 25 months.
| Stable | Converted | P | |
|---|---|---|---|
| Number | 60 | 18 | |
| Age (years) (SD) | 74.1 (3.7) | 75.3 (4.1) | 0.27 |

| SBP (mmHg) (SD) | 132.6 (15.5) | 135.1 (9.3) | 0.54 |
| DBP (mmHg) (SD) | 77.1 (7.7) | 73.8 (7.3) | 0.13 |
| Cholesterol (mmol/L) (SD) | 1.4 (0.5) | 1.7 (0.7) | 0.19 |
| Blood glucose (mmol/L) (SD) | 5.5 (1.3) | 5.8 (1.7) | 0.41 |

P value refers to differences between groups of stable and converted in age, sex, education, MMSE, SBP, DBP, cholesterol, and blood glucose. Education refers to self-reported years of education. The difference of sex was determined by Chi-square test, the difference in other variables was determined by the student’s t-test. MMSE, mini-mental state examination; SBP, systolic blood pressure; DBP, diastolic blood pressure.
