“Contrast” enumerates the five statistical comparisons specified by “Experiment” and “Protocol”; see Fig. 1. “Sign. probes” are the number of probes on the Illumina microarray (total probes: 47323) with significantly different signals in PAXgene compared with Tempus (* p < 0.05); “Sign. Transcripts” are the number of distinct transcripts targeted by the significant probes
