Disease-specific survival (A) and recurrence-free survival (B) in 235 patients illustrated by Kaplan Meier curves. Disease-specific survival in patients with a putative low-risk disease preoperatively, that is endometrioid grade 1 or 2 (C). P-values are calculated by the Mantel-Cox log rank test. Low GDF-15 is the two lower tertiles, 1. and 2. combined. High GDF-15 is the 3. tertile. Number of cases are given in each category and in parenthesis number of disease-specific deaths or recurrence.
