Result by cancer type indicated that H19 expression was significantly related to distant metastasis in nongastrointestinal tumors (OR = 3.85, 95% CI = 1.31–11.36, P = 0.01, random-effect) and also in the gastrointestinal tumors (OR = 0.34, 95% CI = 0.15–0.78, P = 0.01, random-effect). Here, H19 is linked to digestive system neoplasm.
