ERBB2 and breast carcinoma: We have extended the analysis to investigate whether the vector-computation results exhibit sensitivity to either the ER or Her2 breast-cancer biomarkers, by performing separate L-B analyses for the ER( +) and ER( −) subjects (n = 13 and 5, respectively), and for the Her2( +) and Her2( −) subjects (n = 9 and 9).
