Identification and validation of core genes. (A) Core genes are screened by taking the intersection of ARGs, NAR-related targets, and diagnostic marker genes from machine learning screening. (B) Validation of differential expression of the core gene IGFBP3 in the training set dataset. (C) Differential expression of the core gene IGFBP3 in the validation set dataset. (D) Validation of the diagnostic efficiency of IGFBP3.
