Figure 9. (A) Summary plot of different machine learning models. (B) ROC curves of support vector machine. (C–E) 3D scatter plot after principal component analysis of hub genes. (F) Expression values of hub genes between different groups in GSE53482. (G) Expression values of hub genes between different groups in GSE61629. ***: P < 0.001, **: P < 0.01, *: P < 0.05, ns: P> 0.05. (H) Expression of the hub genes EPB42, CALR, SLC4A1, MPL between PMF patients and healthy donors collected at our institution.
