We then assessed ID3 and SLC22A4’s discriminatory ability for stroke patients and healthy controls, respectively, and a good discriminatory ability was found for both the discovery and validation sets (discovery set: ID3 AUC=0.893, 95%CI=0.819-0.954; SLC22A4 AUC=0.891, 95%CI=0.819-0.951; validation set ID3 AUC=0.898, 95%CI=0.830-0.951; SLC22A4 AUC=0.940, 95%CI=0.874-0.988) (Figure 5E–5H). Here, SLC22A4 is linked to Stroke.
