Summary risk estimate reported for the association between statin use and proximal colon cancer by subgroup. ^aExcluding Cheung 2019 [70] due to different outcome measure, i.e., post-colonoscopy proximal colon cancer within 3 years and Jacobs 2006 [71] for which no association was found but no specific risk estimate was reported; ^bEstimates were log-transformed prior to generation of the pooled estimate. CI Confidence interval, I² test for heterogeneity between studies within subgroups, Meta-regression p-value p-value for evidence of between subgroup heterogeneity
