FIG. 6.
Effect of the number of genes in the biomarker on prediction of ERα modulation. A, Comparison of predictions of ERα activation across 327 biosets in the MCF-7 compendium using the original ERα biomarker and shortened versions (illustrated in inset). The bioset predictions were rank-ordered based on the −log(P value) derived using the full-length biomarker. Linear trend lines were added to illustrate the intersection with −log(P value) = 4. B, Relationships between the length of the biomarker and percentage of biosets falsely predicted to be negative for activation or suppression.
