Table 2 Results of multivariable analysis.
B | OR | 95% CI | p value | |
---|---|---|---|---|
Aged ≥90 years | 0.4 | 1.5 | 0.7–3.1 | 0.255 |
Disturbance of consciousness | 0.9 | 2.6 | 1.3–5.2 | 0.008 |
Shock index ≥1* | 0.4 | 1.4 | 0.6–3.5 | 0.451 |
Oxygen administration ≥5 L/min | 1.0 | 2.6 | 1.3–5.4 | 0.009 |
* Shock index was calculated as heart rate divided by systolic blood pressure. B – regression coefficient; OR – odds ratio; CI – confidence interval. p values were calculated by logistic regression analysis using 4 items as covariates. |
