Table 4 Results of the regression analysis for in-hospital mortality listed by strength of contribution (absolute value of B)

From: Elderly patients undergoing mechanical ventilation in and out of intensive care units: a comparative, prospective study of 579 ventilations

Predictor Regression coefficient (B) SE of B Odds Ratio (OR) 95% CI of OR P
Sepsis as the reason for ventilation (0 = No, 1 = Yes) 0.918 0.295 2.505 (1.405; 4.468) 0.002
Pulmonary edema as the reason for ventilation (0 = No, 1 = Yes) - 0.746 0.358 0.474 (0.235; 0.957) 0.037
Charlson score (0 to 37) 0.123 0.049 1.131 (1.028; 1.245) 0.011
Acute Physiology Score points (0 to 60) 0.056 0.020 1.058 (1.016; 1.101) 0.006
Age (years) 0.027 0.008 1.027 (1.011; 1.044) 0.001
*ICU ventilation (0 = No, 1 = Yes) -0.186 0.341 0.830 (0.426; 1.619) 0.584
*Pre-hospitalization FIM score (18 to 126) -0.005 0.004 0.995 (0.987; 1.004) 0.258
  1. *These variables were not statistically significant, but their importance is critical.
