Risk of colorectal neoplasm in patients with acromegaly: A meta-analysis

Figure 3 Funnel plot of selected studies examining colon adenoma prevalence in acromegaly patients and controls. No evidence of publication bias found (P = 0.711, by adjusted rank correlation test). Similarly no evidence of publication bias was found for the other colon neoplasias studied, i.e. colon hyperplastic polyps and colon cancer (see results, Table 2).
