| Prediction | Harrell’s C-Statistic (95% CI) | Difference (95% CI) |
|---|---|---|
|
| ||
| 10-year risk | 0.726 (0.689 to 0.765) | Reference |
| 30-year risk | ||
| Hard ASCVD outcome model (without BMI)a | 0.749 (0.714 to 0.784) | 0.023 (−0.005 to 0.047) |
| Hard ASCVD outcome model (with BMI) | 0.738 (0.704 to 0.775) | 0.011 (−0.018 to 0.040) |
| Expanded CVD outcome model (without BMI) | 0.755 (0.720 to 0.789) | 0.028 (0.001 to 0.053)b |
| Expanded CVD Outcome Mode (with BMI) | 0.740 (0.705 to 0.776) | 0.014 (−0.016 to 0.043) |
See Supplemental Table 1 for risk factors and outcomes used for each risk prediction.
