Table 1.

Patients’ characteristics: Patients’ characteristics in cases diagnosed for intra-(ICG) and extracapsular (ECG) are displayed. Grading was binarized for statistical analysis. Low/high grade refers to the serous subtype only while G1/2/G3 represents grading of non-serous cases. p-values derive from Fisher’s exact test (in the case of categorical variables) and Student’s t-Test (in the case of continuous variables) are shown. ns: not significant.
