Figure 3From: Hepatitis C virus infection and the risk of intrahepatic cholangiocarcinoma and extrahepatic cholangiocarcinoma: evidence from a systematic review and meta-analysis of 16 case-control studiesForest plot of intrahepatic cholangiocarcinoma risk associated with HCV infection. A statistically significant positive association between HCV infection and ICC incidence was found (OR = 3.38, 95% CI, 2.72 to 4.21, P < 0.001) in a random-effects model in the meta-analysis of 13 case-control studies.Back to article page
