(A) The difference of relevant miR-193a-3p expression between tumor smaller than 5cm and tumor larger than 5cm, P=0.041. (B) The difference of relevant miR-193a-3p expression between single tumor node and multiple tumor nodes, P=0.009. (C) The difference of relevant miR-193a-3p expression between negative infection and positive infection of HCV, P=0.017.
