Pattern of expression of genes used to determine the prognosis and clinical characteristics of 198 breast cancer patients. Panel A shows the pattern of expression of the 63 marker genes in a series of 198 consecutive patients with breast carcinoma. Each row represents the prognostic profile of the 63 marker genes for one tumor, and each column represents the relative level of expression of one gene. The tumors are numbered from 1 to 198 on the y axis, and the genes are numbered from 1 to 63 on the x axis. Panel B shows the time in years to distant metastasis as a first event for those in whom this occurred, and the total duration of follow-up for all other patients. Panel C shows the living status. The black dots represent the number of patients who died.
