Note: All variables marked were assessed against log(u11‐dTXB:Cr) to achieve a linear relationship for model validity, normal distribution of residuals and even variance of residuals.

Abbreviations: ALT, alanine aminotransferase; CI, confidence interval; CRP, C‐reactive protein; HCT, hematocrit; IMHA, immune‐mediated hemolytic anemia; PLT, platelet count; T.bil, total bilirubin; u11‐dTXB:Cr, urinary 11‐dehydrothromboxane B₂‐to‐creatinine ratio; WBC, total white blood cell count.
