Comparison of gene expression induced in response to stimulation with PPD and with BCG. Data was normalized using a variance stabilization method (VSN2) and genes significantly induced by stimulation with PPD and BCG, as compared with the unstimulated control, were combined into a single gene list: the scatter of these genes in response to either stimulation is shown. Spearman's rank test was used to assess the correlation (r = 0.965, p < 0.000001). The lines indicate a greater than 2 fold difference in expression.
