Fig. 1: Case flow diagram for endometrioid ovarian carcinoma (EnOC) cases with matched whole exome sequencing (WES) and hormone receptor expression data.

174 EnOC cases with unsupervised hormone receptor subgroup available from the previous study24. 216 EnOC cases identified subsequent to the unsupervised subgrouping study of hormone receptor expression patterns with available WES23; these cases were classified by available oestrogen and progesterone receptor (ER and PR) immunohistochemistry data, using a histoscore threshold of ≥150. HGS, high grade serous; WT1, Wilms’ tumour 1; QC, quality control; PR, progesterone receptor; ER, oestrogen receptor.
