Kaplan-Meier survival analysis.

<p>(A) Kaplan-Meier (KM) survival curves at the 120-month follow up point (TFU). (B) Kaplan-Meier metastasis-free survival (MFS) curves at the 120-month follow up point. For both TFU and MFS KM survival curves, the median of the CD90 H-score was used to discriminate patients with high CD90 expression (red line) and low CD90 expression (blue line). P-values were obtained by log-rank tests.
