Hanifin JM et al. The eczema area and severity index (EASI): assessment of reliability in atopic dermatitis. Exp Dermatol. PMID: 11168575. Adult multipliers are head 0.1, upper limbs 0.2, trunk 0.3, and lower limbs 0.4, each times area (0–6) times the sum of erythema, edema, excoriation, and lichenification (each 0–3). Severity strata are those from the interpretability study (Leshem YA et al. Br J Dermatol. PMID: 25580670). (2001)
