Association between EPHA1, EPHA2 and EFNA protein expression in primary tumors and clinicopathological parameters in patients with ccRCC.

The chi-squared test was used to evaluate the associations of the categorized variables. The p values were then corrected for multiple comparisons (n = 12) by using the method of Benjamini and Hochberg. P values highlighted in bold indicate statistically significant associations.1When no clinical (N0) or pathological (pN0) lymph node metastases were noticed the lymph node status was considered as pN0/N0.2For M status only 225 (EPHA1) and 229 (EPHA2) cases, respectively, were available due to one case with unknown M status.
