BSG and cancer: Kaplan-Meier analyses showed a relation between CD147 expression and the probability of cancer-specific survival, in that high expression levels were associated with poor survival based on a cutoff determined by conditional inference tree models (Hazard Ratio (HR) = 5.5, 95% Confidence Interval (CI) (2.5, 12.1); P(logrank) = 2e−06) (Figure 1D).
