Overall P values come from Wald tests of global null hypothesis in multivariate logistic regression with all characteristics included. For these multivariate models only, race/ethnicity was parameterized as yes, no, or missing.
*
P value from the chi-square test. For ordinal characteristics (age, length of stay), Mantel-Haenszel chi-square P values are reported.
