Model Performance and the Predictive Values of the PNI, Albumin, or Total Lymphocyte Count for Total Mortality
| HR (95% CI) | P Value | AIC | NRI (95% CI) | |
|---|---|---|---|---|
| PNIa, 1 SD=0.16 | 0.79 (0.73–0.87) | <0.001 | 6738 | 2.4% (0.9–3.9%) |
| Albumin, 1 SD=0.53 mg/dL | 0.83 (0.76–0.90) | <0.001 | 8701 | 1.0% (−0.3% to 2.4%) |
| Total lymphocyte count, 1 SD=0.72×109/L | 0.81 (0.72–0.90) | <0.001 | 6920 | 0.9% (−0.2% to 2.0%) |
The Cox proportional hazard model has included age, sex, estimated glomerular filtration rate, left ventricular ejection fraction, sodium, and systolic blood pressure. AIC indicates Akaike information criterion; CI, confidence interval; HR, hazard ratio; NRI, net reclassification improvement; PNI, prognostic nutritional index.
