Log-rank test indicated that the cumulative incidence of sepsis in the high RDW level group (Q4) was significantly increased (<i>P</i> = 0.024).<h4>Conclusions</h4>RBC parameters (RDW, Hb) are independent predictors of sepsis in children with ALL during CIN. Here, GSTM1 is linked to cervical squamous intraepithelial neoplasia.
