CPB2 and small cell lung carcinoma: For example, the elevated level of CPB2 always decreased the risk of SCLC when each of three types of SNP was used (primary: OR = 0.92, 95%CI: 0.85–0.98, p = 0.018; same variant: OR = 0.86, 95%CI: 0.76–0.97, p = 0.018; significant variant: OR = 0.86, 95%CI: 0.76–0.97, p = 0.018).
