Per LC subtypes, Table 1 presented that the risks of LC were similar for different LC types with GSTM1 deletion for all populations combined (non-small cell LC [NSCLC]: RR = 1.11, p < 0.0001; Mixed LC types: RR = 1.10, p < 0.0001). The gene discussed is GSTM1; the disease is non-small cell lung carcinoma.
