Identify and validate diagnostic efficacy and expression in psoriasis of diagnostic biomarkers. (A and C) ROC analysis of PA-IRGs in validation sets GSE14905 and GSE57691. The greater the AUC, the higher the diagnostic value. (B and D) The expression level of diagnostic biomarkers in GSE14905 and GSE57691. P-value < 0.05 was considered statistically significant. (EH) IHC staining (x200) and histogram of mean optical density of diagnostic biomarkers in psoriatic lesions and healthy skin tissue. * p < 0.05, **P<0.01, the difference was statistically significant.
