Multivariate Analysis (Logistic Regression) of Factors Associated with Discordance between C-Reactive Protein and Erythrocyte Sedimentation Rate*,†
| High ESR and normal CRP (n = 72) | High CRP and normal ESR (n = 208) | |||
|---|---|---|---|---|
| Factor | OR (95% CI) | P value | OR (95% CI) | P value |
| Sex (male) | 0.815 (0.448–1.481) | .502 | 0.699 (0.483–1.012) | .058 |

CI, confidence interval; CRP, C-reactive protein; ESR, erythrocyte sedimentation rate; OR, odds ratio.
↵* High CRP is defined as >0.5 mg/dL (>5 mg/L); high ESR is defined as >20 mm/h for men and >30 mm/h for women.
↵† A total of 1472 cases were entered into the equations. The odds ratio (adjusted for all listed variables and alcohol consumption, smoking, metabolic syndrome, and physical activity).
