Cox proportional hazards regression analysis(30-d mortality)
| Prognostic Factor | Univariate analysis | P value | Multivariate analysis | P value | ||
|---|---|---|---|---|---|---|
| Unadjusted HR | 95% confidence interval | HR | 95% confidence interval | |||
| Age | 1.24 | 1.09–1.42 | 0.001 | 1.25 | 1.04–1.50 | 0.017 |
| Hypotension frequency | 1.55 | 1.22–1.96 | 0.000 | 1.19 | 0.85–1.65 | 0.311 |
| Duration of hypotension | 1.07 | 1.02–1.12 | 0.004 | 1.03 | 0.95–1.11 | 0.513 |
| AKI | 14.57 | 2.66–79.56 | 0.002 | 18.12 | 2.60–126.39 | 0.003 |
Factors of P < 0.05 in the univariate analysis were included in the multivariate analysis. All the variables for regression analysis were listed in the chart, among which Age and AKI were significant risk factors for 30-d mortality in this study
