摘要	The SCORAD is a comprehensive clinician-administered tool for measuring the extent and severity of atopic dermatitis (eczema). Developed by the European Task Force on Atopic Dermatitis in 1993, it combines objective clinical assessment with subjective symptom reporting. It is the gold standard for atopic dermatitis severity in clinical trials and dermatology practice.	The EASI is a structured, clinician-administered tool for assessing the extent and intensity of atopic dermatitis across the body. Developed by Hanifin and colleagues in 2001, it divides the body into four regions with weighted area factors, ensuring proportional contribution to total score. EASI has become the primary objective severity measure in atopic dermatitis clinical trials and is recommended by international regulatory authorities (FDA, EMA).	The Pruritus Visual Analog Scale (VAS) is a simple, single-item patient-administered tool measuring itch intensity on a continuous 0–10 (or 0–100) scale. Adapted from the original VAS for pain, it is one of the most frequently used outcome measures in dermatological research and clinical practice due to its simplicity, brevity, and responsiveness to treatment. Pruritus VAS is essential in trials of antipruritic therapies and in conditions where itching is a primary complaint (atopic dermatitis, psoriasis, pruritus ani, lichen planus).
