Figure 1. Relative Performance ROC curves.

Figure 1

Multivariable logistic regression generated ROC curves with baseline serum PSA level coupled with either secretion capcity biomarkers: total expressed Vol (μL) and total RNA (ng) (secretion capacity model,yellow line); non-zero natural log transformed values for the average level of Type III and Type VI TMPRSS2:ERG expression and the average level of Type III and Type VI TMPRSS2:ERG expression normalized to the amount of RNA used in the cDNA reaction (TMPRSS2:ERG model, blue line).
