An interaction analysis between pre-transplant serum TNFSF13 levels and adjusted variables for recurrent IgA nephropathy
| Variables | Adjusted HR | 95% CI | p-value for interaction |
|---|---|---|---|
| Recipient age ≥ 50 years | 0.981 | 0.915–1.052 | 0.597 |
| Donor age ≥ 50 years | 1.017 | 0.976–1.060 | 0.427 |
| HLA full matches | 1.054 | 0.960–1.158 | 0.266 |
| ABO mismatch | 0.985 | 0.830–1.170 | 0.864 |
| Follow up duration ≥2000 days | 1.030 | 0.993–1.069 | 0.115 |
| Gd-IgA1 (units/ng IgA) | 0.995 | 0.985–1.006 | 0.370 |
| Living related donor | 1.046 | 1.008–1.085 | 0.018 |
HR: hazard ratio, 95% CI: confidence interval. The hazard ratio was expressed as 1 units of Gd-IgA1/ng IgA increase
