| Low Alb level at week 0 | 0.022 | 3.431 | 1.196 - 9.846 |
| Low Hct level at week 30 | 0.531 | 1.258 | 0.613 - 2.582 |
| High CRP level at week 30 | 0.007 | 2.643 | 1.310 - 5.332 |
| Low Alb level at week 30 | 0.819 | 0.916 | 0.434 - 1.935 |
After univariate analysis, variables with P < 0.05 were included in the multivariable Cox model. CRP: C-reactive protein; Alb: albumin; CI: confidence interval.
