Comparison of the signals between emphysematous and fibrotic lesions, fold-change and P value intersection, and hierarchical clustering analysis. Paired t test results summary comparing between emphysematous and fibrotic lesions on the microarray data (a), volcano plot representing the point of intersection of fold-change (FC) (emphysema vs. fibrosis) relative to P value (emphysema vs. fibrosis) (b), and heat map built as the result of hierarchical clustering analysis (c). Emp 1_singal, Emp 2_singal, and Emp 3_singal indicate the signals detected in the specimens of emphysematous lesions in case 1, case 2, and case 3, respectively. Fbr 1_singal, Fbr 2_singal, and Fbr 3_singal indicate the signals detected in the specimens of fibrotic lesions in case 1, case 2, and case 3, respectively.
