We estimated the risk associations between genetic polymorphisms and APL as odds ratio (OR) 1.10 (95% CI 0.72–1.68) for the GSTM1 null genotype and OR 1.68 (95% CI 1.07–2.65) for the GSTT1 null genotype, respectively (Supplementary Table 3). The gene discussed is GSTM1; the disease is acute promyelocytic leukemia.
