Logistic regression analysis showing odds ratio for physician’s change in approach to prescribing antibiotics: Pre-CRP testing unwilling to prescribe antibiotics changing to prescribe antibiotics post-CRP testing and vice versa as dependent variable (1).
| Unadjusted odds ratio (CI 95%) | p Values | Adjusted odds ratio (CI 95%) | p Values | |
| Sex (female 1) | 1.5 (0.81–2.7) | 0.21 | – | – |
| Educational status (GP 1)1 | 1.5 (0.81–2.7) | 0.20 | – | – |
| Differences between estimated and measured CRP (mg/L)2 | 1.02 (1.01–1.03) | <0.001 | 1.03 (1.01–1.04) | <0.001 |
