Funnel plot of 13 studies; (b) no publication bias was found between HCV infection and ICC risk using Begg’s adjusted rank correlation test (P = 0.951) and Egger’s regression asymmetry test (P = 0.606). Funnel plot of 5 studies; (c) no publication bias was found between HCV infection and ECC risk using Begg’s adjusted rank correlation test (P = 0.221) and Egger’s regression asymmetry test (P = 0.495).
