Table 3.
Stepwise generalized linear regression model for 30-day mortality (AIC=125.82). The correlated variables were age (OR 1.09, p=0.003), residence in a retirement home (OR 6.91, p=0.031), hospital readmission within 30 days of the first visit to the ED (OR 7.06, p=0.005), chronic kidney failure (OR 6.14, p=0.006) and heart rate (OR 1.04, p=0.022).
