Coding of variables: PSMC2 was coded as 0 (low), and 1 (high). Age was coded as 0 (≤55 years), and 1 (>55years). Sex was coded as 0 (male), and 1 (female). Tumor size was coded as 0 (≤5 cm), and 1 (>5 cm). Tumor differentiation was coded as 0 (I and II), and 1 (III and IV). TNM was coded as 0 (I), and 1 (II and III). Liver cirrhosis was coded as 0 (NO), and 1 (YES). CI, confidence interval. The bold values are considered as statistically significant. Some cases were not available for the information.
