Summary of the overlap study of the two astrocytoma progression marker data sets. A. Internal consistency of the methods under comparison. k = Khatua et al. data set⁵¹; vdb = van den Boom et al. data set⁵² B. Number of significant genes that overlap between the two data sets in the significant gene list for each method. C. Comparison (% overlap) of methods in the k data set. D. Comparison (% overlap) of methods in the vdb data set
