Diagnostic efficacy and external verification of diagnostic markers. (A, B) The 4 diagnostic markers expression in seven DKD pooled datasets (A) and external datasets (B). (C, D) Receiver operating characteristic (ROC) curves assessing the diagnostic efficacy of four diagnostic markers in seven DKD combined datasets (C) and GSE142025 dataset (D). (E, F) Correlation analysis of gene expression levels with creatinine (E) and glomerular filtration rate (GFR) (F). ****P < 0.001, ***P < 0.005, **P < 0.01, *P < 0.05.
