Propensity score-adjusted linear regression performed to analyze continuous data with bootstrapping for non-normal distribution and binary logistic to analyze dichotomous data.
A p value <0.05 was considered statistically significant.
DD, direct discharge; EPR, electronic patient record; NP, not performed (as the number of observations was too small to perform bootstrapping (if applicable) and subsequent regression).
