For example, the TCGA (30) and Predictor of high-grade serous Ovarian carcinoma molecular subtype (PrOTYPE) (33) studies had only 1% and 8.4% LTS cases, respectively, and may have been underpowered to detect the combined effects of immune cell infiltrates and C4/DIF subtype on LTS shown here. This evidence concerns the gene C4A and ovarian serous carcinoma.
