Table showing the coefficient of correlation with a Pearson correlation test (Correlation) between clinical parameters and BT3.2 staining intensity observed in the intra-epithelial area of ovarian tumor tissues. Grade and stage were evaluated according to the FIGO classification as described in Materials and Methods. Res. Disease is the amount of residual disease at primary resection of the tumor as classified in Table 1. Recurrence is the first event of ovarian cancer recurrence after the primary resection of the tumor. CA125 =  blood serum level CA125 at the date of primary resection of the ovarian tumor. P is the p value from Pearson correlation test. N is the number of cases included in the statistical analysis.
