Probes were mean centered across experiments.

Expression data for genes represented on both platforms were mean centered across the experiments.

Briefly, ER+ samples were extracted from the FBC reference dataset and genes were mean centered across these samples.

The data were MAS5 normalized, mean centered across assays and samples were classified into molecular subtypes based on gene expression centroids from Hu et al. [ 6] as described [ 17].

For each of 429 ER+ tumors represented on the arrays, we computed a PI3K score, which was the sum of the phosphoprotein levels (mean-centered across tumors) of Akt, mTOR, GSK3, S6K, and S6, minus the total levels of pathway inhibitor PTEN (that is, PI3K score = pAkt + pmTOR + pGSK3 + pS6K + pS6-PTEN); a high PI3K score would indicate high pathway activity.
