Cox regression analyses for survival in patients with SLE.
| Multivariate | ||
|---|---|---|
| HR (95% CI) | p | |
| Age (ref: <65 years) | 2.57 (1.43–4.61) | 0.002 | 
| CCI score (per 1 score increase) | 1.17 (1.07–1.28) | <0.001 | 
| Hemoglobin (per 1 g/dL increase) | 0.74 (0.54–0.98) | 0.035 | 
| Serum creatinine (per 1 mg/dL increase) | 0.90 (0.83–0.98) | 0.016 | 
| Systolic blood pressure (per 1 mmHg increase) | 1.02 (1.01–1.04) | <0.001 | 
The multivariate analysis was adjusted for the disease group, age, sex, CCI score, hemodialysis vintage, ultrafiltration volume, Kt/Vurea, hemoglobin, serum albumin, serum creatinine, serum phosphorus, serum calcium, systolic blood pressure, and diastolic blood pressure and was performed using the backward mode. Abbreviations: HR, hazard ratio; CI, confidence interval; SLE, systemic lupus erythematosus; CCI, Charlson comorbidity index.
