Data are presented as the No. (%) or median (interquartile range). Steroid dosages are expressed as corresponding amounts of prednisolone. Categorical variables were compared using Fisher's exact test, and continuous variables were compared using the Mann-Whitney U test.

PCP: pneumocystis pneumonia; SOFA: Sequential Organ Failure Assessment; LDH: lactate dehydrogenase; TMP-SMX: trimethoprim-sulfamethoxazole.
