Preoperative predictors of short-term survival after hepatectomy for multinodular hepatocellular carcinoma

Figure 1 Distribution of tumor size according to tumor differentiation and presence of microvascular invasion, showing median, 25th-75th percentile box and complete range of measurements. A: Distribution of total tumor size according to tumor differentiation (P = 0.003); B: Distribution of total tumor size according to presence of microvascular invasion (P < 0.001); C: Distribution of the largest tumor size according to tumor differentiation (P = 0.008); D: Distribution of total tumor size according to tumor differentiation and presence of microvascular invasion (P < 0.001). The tumor size was associated with presence of microvascular invasion and poor tumor differentiation. MVI: Microvascular invasion.
