Identification of the DEGs between COPD and NSCLC

For {"type":"entrez-geo","attrs":{"text":"GSE106899","term_id":"106899"}}GSE106899, based on the logCPM values, the DEGs between COPD and COPD with NSCLC were identified by the edgeR package. For {"type":"entrez-geo","attrs":{"text":"GSE12472","term_id":"12472"}}GSE12472 and {"type":"entrez-geo","attrs":{"text":"GSE12428","term_id":"12428"}}GSE12428, the classical Bayesian method provided by the limma package was used to analyze the DEGs ²⁰ (Version 3.10.3, http://www.bioconductor.org/packages/2.9/bioc/html/limma.html). The Benjamini & Hochberg method was used to perform multiple test calibration on the p.value and logFC values of the above genes to obtain the corrected p value (adj.P.Value). The adj.P.Val<0.05 and |logFC|>0.585 were selected as the threshold for the following analysis.
