a
p < 0.001 for all HD groups for all 3 outcomes, except survival to discharge for HD1 where p = 0.002.
b
A cerebral performance category score of 1 or 2 (range, 1–5).
c
HD1 was defined as cardiac arrest event occurring on hospital day 1, HD2–7 as event on days 2–7, and HD>7 as event after 1 week of hospitalization.
d
Regression adjusted for sex, age, and event location.
e
p value for adjusted odds ratio.
