Comparison of primary outcome measures between intervention and control populations at study completion analysed at patient and cluster level.
| Evidence of primary outcome in clinical record | Intervention n (%) | Control n (%) | Odds ratioa (95% CI) | Adjusted odds ratiob (95% CI) | P-value | ICC (95% CI) |
|---|---|---|---|---|---|---|
| Screened for hepatitis C by GP | 51/104 (49) | 25/92 (27) | 2.58 (1.4–4.7) | 3.76 (1.3–11.3) | 0.02 | 0.09 (0.0–0.3) |
| Referral initiated if HCV antibody positive | 44/73 (60) | 13/41 (32) | 3.27 (1.5–7.3) | 3.15 (0.9–10.7) | 0.06 | 0.13 (0.0–0.5) |
