	Mild Psoriasis		Moderate to Severe Psoriasis
	Little/no Psoriasis	1–2% BSA Psoriasis	3–10% BSA Psoriasis	>10% BSA Psoriasis
Proportion of psoriasis patients	51.59%	31.68%	11.38%	5.25%
Mean psoriasis impact on daily life (95%CI)	3.22 (2.37, 4.07)	4.11 (2.97, 5.25)	7.32 (5.31, 9.32)	10 (10, 10)

83.37% of psoriasis patients with a history of physician diagnosis had mild psoriasis (little/no to 1–2% BSA) while 16.63% had moderate to severe disease (3% or greater BSA). Mean psoriasis impact on daily life score increased with increasing psoriasis severity. BSA = body surface area.
