Data are presented as n, mean±sd, n (%) or median (interquartile range), unless otherwise specified. PSI: Pneumonia Severity Index; ED: emergency department; ICU: intensive care unit. ^#: only variables with p-values <0.10 are included; ^¶: amount expressed as the equivalent of normal saline; ⁺: per 5-point increase.
