FIGURE 4 | Identi fi cation, ROC curve analysis, and correlation analysis of STFs in exploration cohort. (A) identi fi cation of STFs by Venn diagrams. (B, C) ROC curve analysis of each STFs in GSE41664 and GSE5281. STF whose AUC values > 0.60 in psoriasis and AD was considered with diagnostic value; STF whose AUC values > 0.80 was considered with high diagnostic values. (D, E) correlation analysis among STFs in GSE41664 and GSE5281. Each cell contains the Pearson correlation coef fi cient and p-value. P-value < 0.05 and Pearson correlation coef fi cient (PCC) > 0. 85 were considered as correlated, while p-value < 0.05 and PCC > 0. 95 strongly correlated. * p-value <0.05; ** p-value <0.01.
