EPHX1 and colorectal carcinoma: As for the association of the EPHX1 His139Arg with CRC risk, the study that had the most influence on the overall pooled estimates (Figure S2B) seemed to be the one conducted by Robien et al. [25]; however, the sensitivity analysis showed that the ORs were 0.92 (95% CI: 0.85, 0.99) and 0.91 (95% CI: 0.83, 0.99) before and after the removal of that study, respectively, indicating high stability of the results.
