  • The levels of the first three biomarkers are different in men and women, denoted by M and F, respectively.

  • ALT, alanine transaminase; AST, aspartate aminotransferase; CRP, C reactive protein; F, female; HB, haemoglobin; HCT, haematocrit; LDH, lactate dehydrogenase; M, male; RBC, red blood cell; WBC, white blood cell.
