Classification of Spanish patients with RA at CVD risk equation cutoff values based on sensitivity or specificity set at 80% in ROC analysis, or conventional recommendations.
| Equation | Cutoff Value, % | Sensitivity, % | Specificity, % | PPV, % | NPV, % | Correct Classification |
|---|---|---|---|---|---|---|
| Framingham score | ≥ 7.3 | 80 | 63 | 66 | 76 | 71 |
| ≥ 10.8 | 65 | 80 | 75 | 70 | 72 | |
| ≥ 20 | 25 | 95 | 85 | 57 | 61 | |
| SCORE | ≥ 0.5 | 80 | 58 | 65 | 76 | 72 |
| ≥ 1.5 | 50 | 80 | 67 | 59 | 64 | |
| ≥ 5 | 8 | 99 | 86 | 52 | 54 |
RA: rheumatoid arthritis; CVD: cardiovascular disease; ROC: receiver-operator curve; PPV: positive predictive value; NPV: negative predictive value; SCORE: Systematic COronary Evaluation Score.
