Hemoglobin (Hb), platelet (Plt) count, white blood cell count, and neutropenia levels were 94.29 ± 25.74, 215.07 ± 158.07, 8.45 ± 8.42 and 6.10 ± 6.62 in the nonsurvival group, and 110.42 ± 19.23, 352.06 ± 164.66, 19.74 ± 22.67, and 66.67 ± 19.26 in the survival group. This evidence concerns the gene GSTM1 and neutropenia.
