The Identification of Childhood Asthma Progression-Related lncRNAs and mRNAs Suitable as Biomarkers Using Weighted Gene Coexpression Network Analysis

Figure 4

Principal component analysis (PCA) of the identified genes in the coexpression network. Three-dimensional diagrams of the sample distribution based on PC1, PC2, and PC3 in GSE65204 (a) and GSE19187 (b). The black dots represent the healthy samples, and the red triangles represent the asthma samples. The X-, Y-, and Z-axes represent PC1, PC2, and PC3, respectively. Receiver operating characteristic (ROC) curves in GSE65204 (c) and GSE19187 (d). The figures in brackets represent specificity and sensitivity, respectively.
