As shown in Figure 4B, AFP [OR: 131.79 (95% CI 3.41, 5092.94), p = 0.009], viral hepatitis [OR: 50.78 (95% CI 3.54, 727.86), p = 0.004] and sonographic score [OR: 3.72 (95% CI 1.56, 8.91), p = 0.003] were independent factors that distinguish HCC and IPT. Here, AFP is linked to animal viral hepatitis.
