  1. aThe P values were obtained by the chi-square test for in-hospital death
  2. bFor example, C-reactive protein, complement activity
  3. cFor example, viral antibody tests, β-D-glucan assay
  4. dFor example, blood type test, Coombs test
  5. # Not significant
  6. † Significantly associated with decreased risk of death
