Histograms showing circulating levels of miR-122 according to the etiology of the underlying liver disease (representing median with error bar showing the third quartile). Patients with viral HCC had statistically significantly higher levels of circulating miR-122 compared to patients with alternative etiologies (p = 0.006). The median of miR-122 circulating levels in patients with viral etiology is 2.91 fc [1.62–9.82], a value statistically significant higher compared to the level registered in patients with alternative etiologies (1.76 fc [0.86–2.86]; p = 0.006). ** p ≤ 0.01.
