Validation of the Atopic Dermatitis Control Tool (ADCT©) using a longitudinal survey of biologic-treated patients with atopic dermatitis

Table 7 Average reduction in ADCT total score by improvement in Patient Global Assessment of Disease (PGAD) and Dermatology Life Quality Index (DLQI)

	Overall sample		Uncontrolled patients (ADCT ≥7 at baseline)
	N	Mean reduction	N	Mean reduction
Reduction in ADCT total score per 1-level improvement in PGAD^a	1570	5.30*** (5.14, 5.46)	1479	5.43*** (5.27, 5.59)
Reduction in ADCT total score per 1-level improvement in DLQI bands^b	1574	5.20*** (5.05, 5.35)	1483	5.42*** (5.27, 5.58)
Reduction in ADCT total score per 4-point improvement in DLQI total score^b	1574	3.90*** (3.80, 4.00)	1483	4.03*** (3.92, 4.12)

***p < 0.001; ^aPatients who reported excellent PGAD at baseline were excluded from this analysis due to lack of variability; ^bNo patients had 0 or 1 DLQI scores at baseline and therefore no patients were excluded from this analysis
