Multivariate Cox regression analysis indicated that patients with low expression of ERCC1 and BRCA1 attained 0.43 (OR=0.43, 95%CI=0.27-0.89) and 0.37 (OR=0.37, 95%CI=0.22-0.66) fold risk of death from NSCLC (Fig.1 and Fig.2). The gene discussed is ERCC1; the disease is non-small cell lung carcinoma.
