Figure Lengend Snippet: Diagnostic performance of plasma biomarkers for differentiating Alzheimer’s disease (AD) from cognitively healthy controls (HC) based on ROC curve analysis. Receiver operating characteristic (ROC) curves were generated to assess the diagnostic accuracy of plasma biomarkers. The area under the ROC curve (AUC) was used to evaluate biomarker performance: 0.90–1.00, superior diagnostic efficacy; 0.80–0.89, good diagnostic efficacy; 0.70–0.79, moderate diagnostic efficacy; <0.70, poor/substandard diagnostic efficacy. Data are presented as mean ± SEM. Statistical comparisons were performed using the Mann–Whitney U test. hsa_circ_003077 exhibited the highest diagnostic accuracy (AUC = 0.90; 95% CI: 0.82–0.97), followed by NfL (AUC = 0.75) and pTau-217 (AUC = 0.77). AXL and GFAP showed lower diagnostic performance (AUC = 0.63 and 0.69, respectively), while pTau-181 and Tyro3 demonstrated substandard efficacy (AUC = 0.63 each).
Article Snippet: The Human Tyro3 DuoSet ELISA kit (Catalog No: DY8596-05) supplied by R&D Systems (Minneapolis, MN, USA) was used to measure Tyro3 levels, while the Human AXL DuoSet ELISA kit (Catalog No: DAXL00; R&D Systems, Minneapolis, MN, USA) was used to measure AXL levels.
