Comparison of the expression and diagnostic ROC curves of 7 ferroptosis-related hub genes. (A-G) Comparison of the expression of 7 ferroptosis-related hub genes in COPD and healthy samples; (H,I) signaling pathways where the 7 ferroptosis-related hub genes are predominant in COPD and healthy samples; (J-P) diagnostic ROC curves of 7 ferroptosis-related hub genes in COPD and healthy samples. ***, P<0.001. COPD, chronic obstructive pulmonary disease; ROC, receiver operating characteristic; TPR, true positive rate; FPR, false positive rate.
