| Collection Summary: | The study collected plasma samples from all participants at West China Hospital, Sichuan University. These were approved by the Research Ethics Committee of West China Hospital, Sichuan University (Permission number: 2021(790)), and informed consent was obtained from all participants. Patients were diagnosed with RA according to the 2010 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) criteria. The healthy control group consisted of individuals matched in age and gender, with no history or clinical evidence of autoimmune or rheumatic diseases. Blood collection followed standard venipuncture procedures using anticoagulant tubes. Plasma samples were obtained after centrifugation and stored at -80°C. ACPA levels were measured using Elecsys anti-CCP detection on the Cobas® e 801 module (Roche Diagnostics, Mannheim, Germany), with results categorized as positive (≥17.0 U/ml) or negative (<17.0 U/ml). |
