Genes differentially expressed between scleroderma and normal skin biopsies. A Wilcoxon rank sum test (19) was used to select genes that showed significant differences in expression between scleroderma skin biopsies and normal skin biopsies. Shown are the P values for each gene that have been corrected for multiple testing (P < 0.13). The full list of genes differentially expressed between scleroderma and normal biopsies is available in Fig. 6.
