The box plot shows the median and interquartile values. (a) the absolute blood neutrophil count; (b) the absolute blood eosinophil count; (c) the neutrophil/lymphocyte ratio (NLR); (d) the eosinophil/lymphocyte ratio (ELR); (e) the eosinophil/neutrophil ratio (ENR); (f) the eosinophil/macrophage ratio (EMR); (g) the macrophage/lymphocyte ratio (MLR)
