Table 3 Unadjusted and adjusted Cox proportional regression model of PNI and 30-day mortality.
| 30-day mortality | Crude model | P value | Model 1 | P value | Model 2 | P value |
|---|---|---|---|---|---|---|
| HR (95% CIs) | HR (95% CIs) | HR (95% CIs) | ||||
| Low tertile | 1.0 (ref.) | / | 1.0 (ref.) | / | 1.0 (ref.) | / |
| Middle tertile | 0.54 (0.32, 0.92) | 0.023 | 0.50 (0.29, 0.85) | 0.011 | 0.57 (0.31, 1.05) | 0.070 |
| High tertile | 0.37 (0.21, 0.68) | <0.001 | 0.41 (0.23, 0.75) | 0.004 | 0.39 (0.19, 0.80) | 0.011 |
| Values were expressed as hazard ratios (95% confidence intervals). Model 1 was adjusted for age and sex. Model 2 was adjusted for age, gender, hypertension, diabetes mellitus, coronary heart disease, chronic kidney disease, malignancy, white blood cell count, hemoglobin, platelet count, albumin, alanine transaminase, serum creatinine, serum sodium, serum potassium, pH, PO, PCO, bicarbonate, simplified acute physiology score II, and sequential organ failure assessment. | ||||||
