From: High preoperative blood levels of HE4 predicts poor prognosis in patients with ovarian cancer
Kaplan-Meier estimates of survival probabilities using peripheral blood concentrations dichotomized by the median of HE 4 for serous malignant tumors (A) and non-serous malignant tumors (B). The p-value shown is the log rank statistic with the HR with 95% CI calculated using the Cox proportional hazards model. The number of patients at risk in each stratum at time 0 and 60 months after surgery are shown below the axis with the number of deaths (events) to the left.
