Table 2. Spearman correlation analyses between PMS2 levels in either benign or cancer tissue and pathological variables.

To determine the correlation between PMS2 elevation and the pathological variables in Table 1, a Spearman analyses was performed. The resulting coefficients and p-values are listed here. Bolded numbers indicate those variables which significantly correlated with PMS2 elevation.
