From: CircRNA0001859, a new diagnostic and prognostic biomarkers for COPD and AECOPD
CircRNA0001859 expression level was correlated with the transformation from COPD to lung cancer. Spearman correlation analysis was carried out between FEV1/FVC% and circRNA0001859 expression in blood of (a) CDOP and (b) AECOPD patients. c ROC curve analysis of circRNA0001859 expressions for predicting stable COPD risk from HCs; d ROC curve analysis of circRNA0001859 expressions for predicting AECOPD risk from HCs. Three independent biological repeats were carried out for each analysis
