The Risk Factors of in-Hospital Mortality in the Training Set
| Variables | OR | 95% CI | P | |
|---|---|---|---|---|
| Aging | Age<64yrs | 1 | ||
| Age 65~84yrs | 2.224 | 0.691~7.159 | 0.180 | |
| Age≥85yrs | 4.780 | 1.299~17.591 | 0.019 | |
| Pulse≥125/min | 3.782 | 1.139~12.558 | 0.030 | |
| Urea≥11mmol/L | 3.510 | 1.583~7.784 | 0.002 | |
| Hypoproteinemia | Albumin≥35 g/L | 1 | ||
| Albumin 25~34.9 g/L | 4.929 | 1.787~13.595 | 0.002 | |
| Albumin<25g/L | 12.463 | 1.933~80.353 | 0.008 |
Notes: Multiple logistic regression analysis, in-hospital mortality was considered as the dependent variables in a multiple logistic regression analysis with aging, respiratory rate≥30/min, pulse≥125/min, urea≥11mmol/L and hypoproteinemia as independent variables.
Abbreviations: OR, odds ratio; CI, confidence interval.
