| Sensitivity | Specificity | C-statistic* | Univariable logistic regression | Adjusted for age and gender | |||
| OR | P value | OR | P value | ||||
| CRP | 67.8% (66.3–69.3) | 75.9% (75.6–76.2) | 0.78 (0.77–0.78) | 6.6 (6.2 to 7.1) | <0.001 | 4.5 (4.2 to 4.8) | <0.001 |
| ESR | 56.6% (54.4–58.7) | 75.7% (75.4–75.9) | 0.66 (0.65–0.67 | 4.1 (3.7 to 4.4) | <0.001 | 2.9 (2.7 to 3.2) | <0.001 |

*C-statistic calculated using log transformed test results as a continuous variable.
CRP, C reactive protein; ESR, erythrocyte sedimentation rate; PV, plasma viscosity.
