Table 1 Correlative analysis of SIRT7 mRNA levels with clinicopathological features. High tumoral SIRT7 expression was considered > 2-fold up-regulation relative to the adjacent non-tumoral liver. Correlations between SIRT7 and individual clinicopathologic parameters were evaluated using a nonparametric Fisher’s Exact Test
