Table 3.
Hierarchical logistic regression model adjusted odds ratios for individual and hospital characteristics. Characteristics are listed in ranked order by the absolute value of their parameter estimate. For continuous fixed effects the comparison is equivalent to the distance of the interquartile range. Complete list of covariates in Supplemental Table 3.
