Table 4. HRs for the T-cell parameters in relation to early acute allograft rejection (multivariate analysis).
| HR | 95%CI | P | |
|---|---|---|---|
| Age donor (decades) | 1.40 | 1.06–1.84 | 0.016 |
| PRA historic (%) | 1.13 | 1.06–1.21 | <0.001 |
| Genetically related KT | 0.47 | 0.19–1.17 | 0.102 |
| CD4 positive CD28null T cells (cells/μL) | 0.65 | 0.45–0.96 | 0.028 |
*P ≤ 0.05,
**P ≤ 0.01,
***P ≤ 0.001. CI: confidence interval, HR: hazard ratio. The CD4 positive and the CD8 positive CD28null cells are presented with steps of 20 cells/μL. Covariates: age donor, PRA historic, related KT.
