Fig. 4From: From comorbidities of chronic obstructive pulmonary disease to identification of shared molecular mechanisms by data integrationCandidate biomarkers for COPD-comorbidity. Included are the genes selected as candidate biomarkers for FWER < 0.05 (see Methods). For each gene it is shown if it has been associated to Smoking, Aging and/or Physical activity based on gene expression (see Additional file 16: Table S7), DNA Methylation (see Additional file 16: Table S7) or PolySearch-derived [50, 51] text-mining analysis (see Additional file 15: Tables S4, S5 and S6)Back to article page
