Association with clinical parameters.

Contingency tables for the significant association between the angiogenic subtype classification and (A) histological grade, (B) Stage, and (C) debulking in our validation set of 1,606 ovarian cancer patients. It is worth noting that different datasets are annotated using different histological grading and tumor staging systems, with scales ranging from 1 to 3 and 1 to 4. In this study, we simply merged these clinical annotations because we do not have access to the original tumor tissues to perform a standardized histological grading and tumor staging.
