الملخص	The Wells score, developed by Wells et al. in 1994, is a clinical prediction rule that stratifies patients into low, intermediate, or high pretest probability of deep vein thrombosis (DVT). It combines seven clinical features to guide diagnostic testing decisions and reduce unnecessary imaging in suspected DVT patients.	The CHA₂DS₂-VASc score, developed by Lip, Nieuwlaat, and colleagues in 2010, is a 9-point risk stratification tool for predicting annual stroke and systemic thromboembolism risk in patients with atrial fibrillation. It is the recommended score by major cardiology guidelines for guiding anticoagulation decisions.	CURB-65, derived and validated by Lim et al. in 2003, is a 5-point severity of illness score for community-acquired pneumonia (CAP). It assesses confusion, urea nitrogen, respiratory rate, blood pressure, and age ≥65 years to stratify mortality risk and guide admission and treatment decisions.
