Table 5: Results of reduced predictive model with odds ratio for discharge home obtained by logistic regression. Missing data was multiply imputed (n=10 datasets). The reference and contrast columns provide the reference group and contrast used in the calculation of the odds ratio and 95% confidence intervals. Odds ratios for continuous variables reflect the exponentiation of the log-odds when contrasting the observed values at the 75th versus the 25th percentile for each predictor (interquartile odds ratios).
