Figure 6. Kaplan-Meier survival curves within selected clinical subgroups. Kaplan-Meier curves for in-hospital survival were stratified by IVIG use within subgroups defined by admission white blood cell count (WBC), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and serum creatinine. (A) WBC > 10 × 109/L. (B) WBC ≤ 10 × 109/L. (C) ALT > 40 IU/L. (D) AST > 40 IU/L. (E) creatinine >110 μmol/L. (F) creatinine ≤ 110 μmol/L. Patients discharged alive were censored on their actual dates of hospital discharge, and displayed numbers at risk were generated directly from the same survival objects used to estimate the Kaplan-Meier curves. Displayed P values are from log-rank tests.
