KD LDA models with reduced number of variables (listed in descending order by the absolute value of their weights). The model performance was gauged by ROC analysis. Model A, 10-variable score with AUC of 0.95. Model B, 5-variable score with AUC of 0.90. HGB, hemoglobin; EOS, eosinophil; WBC, white blood cell; CRP, C-reactive protein; POLYS, polymorpho-nuclear leukocytes; ESR, erythrocyte sedimentation rate; GGT, gamma-glutamyl transferase; PLTS, platelets; MONOS, monocytes; ALT, alanine aminotransferase.
