ISGA assessed the severity of AD (except scalp and venous access area) on a 5-point scale ranged from 0 (clear) to 4 (maximum severe), where higher scores indicate higher degree of AD. Grades for classification of severity: 0= clear (minor residual hypo/hyper pigmentation, no erythema or induration or papulation, no oozing or crusting), 1= almost clear (trace faint pink erythema, with barely perceptible induration or papulation and no oozing or crusting), 2= mild (faint pink erythema with mild induration or papulation and no oozing or crusting), 3= moderate (pink-red erythema with moderate induration or papulation with or without oozing or crusting) and 4= severe (deep or bright red erythema with severe induration or papulation and with oozing or crusting). Treatment success was defined as an ISGA score of Clear (0) or Almost Clear (1) with at least a 2-grade improvement from baseline.
