From: YKL-40 tissue expression and plasma levels in patients with ovarian cancer
Kaplan-Meier survival curves showing the association between preoperative plasma YKL-40 and overall survival. Plasma YKL-40 is dichotomized in normal vs. elevated plasma YKL-40 levels. The cut-off point is the age-adjusted plasma YKL-40 value corresponding to the 95th percentile in healthy controls. The P-value refers to the log-rank test for equality of strata.
