Serum miRNA expression in 55 samples. The leftmost three bar plots indicate the significant fold changes (> 2 fold) in miRNA expression among the three pairwise comparisons (BP: BTC vs. PC; PN: PC vs. HC; and BN: BTC vs. HC). The directionality of the fold change was presented by green (up) and red (down) colours
