Genes whose expression is associated with molecular treatment response. SAM identified 55 clones representing 54 genes that distinguished poor from good molecular treatment response when considering a false discovery rate of less than 5%. Each column represents 1 sample, each row 1 clone. Variation in expression is displayed as a variation in color. The color scale extends from 0.125- to 8.0-fold of the mean (-3 to 3 in log₂ space), as indicated in the left lower corner. Gray represents data that were omitted because they were not well measured, as described in “Patients, materials, and methods.” Selected clones, their respective accession numbers, fold changes, and functions are shown.
