| Fasting glucose, mg/dL | 140 ± 59 | 91 ± 9 | 102 ± 35 | <0.001 |

| Current smoker | 57 (10%) | 238 (13%) | 295 (12%) | 0.159 |
| Systolic blood pressure, mmHg | 131 ± 16 | 127 ± 17 | 128 ± 17 | <0.001 |
| Hypertension medication use | 417 (76%) | 877 (46%) | 1294 (53%) | <0.001 |
| History of cardiovascular disease | 90 (16%) | 134 (7%) | 224 (9%) | <0.001 |
| Follow-up time, y | 14.1 (10.3, 16.0) | 14.9 (12.5, 16.0) | 14.6 (12.0, 16.0) | |
| Deaths | 220 (40%) | 364 (19%) | 584 (24%) |
Numbers are expressed as mean ± SD and n (%) except for follow-up time, which is expressed as median (IQR). Fasting glucose was missing for one participant without diabetes. P values were calculated based on two-sided two-sample t-tests for continuous variables and two-sided Fisher’s exact tests for categorical variables.
