Kaplan-Meier estimates of ovarian cancer specific and overall survival in all patients according to CD138 expression. Kaplan Meier analysis of (a) overall survival and (b) ovarian cancer specific survival in strata of low and high CD138 expression. The categories of staining were determined by classification and regression tree analysis based on the core score (CS), whereby low expression = CS ≤ 2.25 and high expression = CS > 2.25
