| NAT positive marker | Donation type | Odds ratio* | 95% CI | P value |
|---|---|---|---|---|
| Discriminatory positive HBV NAT | First-time | 4.47 | 1.59–12.54 | <0.05 |
| Repeat | 7.33 | 1.77–30.24 | <0.05 | |
| Discriminatory positive HCV NAT | First-time | 22.35 | 2.92–170.95 | <0.05 |
| Repeat | 58.33 | 3.62–940.02 | <0.001 | |
| Initially NAT reactive, not discriminated | First-time | 3.44 | 0.31–37.92 | >0.05 |
| Repeat | 2.83 | 0.65–12.25 | >0.05 | |
| All | First-time | 6.88 | 3.0–15.76 | <0.001 |
| Repeat | 12.33 | 4.57–33.30 | <0.001 |
