High expression level of HMGA2 is associated with the development of noninfectious pneumonia in patients with MDS. (A) Receiver operating characteristic (ROC) curves showing the association between HMGA2 messenger RNA (mRNA) level in CD34⁺ BM cells and cytopenias in patients with MDS (n = 17). Corresponding AUC values are shown. (B-D) mRNA expression levels of HMGA2 in CD34⁺ BM cells from the indicated groups. The horizontal bar shows the median value. (E) ROC curves showing the association between HMGA2 mRNA level in CD34⁺ BM cells and parameters for disease progression in patients with MDS (n = 17). Corresponding AUC values are shown. (F-H) mRNA expression levels of HMGA2 in CD34⁺ BM cells from the indicated groups. The horizontal bar shows the median value. (I) ROC curves showing the association between HMGA2 mRNA level in CD34⁺ BM cells and major systemic complications in patients with MDS (n = 17). Corresponding AUC values are shown. (J-M) mRNA expression levels of HMGA2 in CD34⁺ BM cells from the indicated groups. The horizontal bar shows the median value.
