^*Data are presented as number (%) unless otherwise specified.

^†Self-reported by patients or their surrogates. Numbers do not sum to group totals because of missing race/ethnicity data in 2.2% of patients.

^‡Numbers do not sum to group totals because of missing payment-source data in <0.01% of patients.
