Figure 4 Associations of IL22 and LCE3C copy numbers among different severities of psoriasis and healthy controls. (A) The distribution of IL22 CNV was different and inversely correlated with the severity of psoriasis. (B) The distribution of LCE3C CNV was different and inversely correlated with the severity of psoriasis. (C) IL22 copy numbers in mild psoriasis are higher than in severe psoriasis and in healthy controls. (D) LCE3C copy numbers in mild, moderate, and severe psoriasis were lower than in healthy controls. Mild – mild psoriasis; Moderate – moderate psoriasis; Severe – severe psoriasis; HC – healthy control; Blue Bar – the correlation between different CNV group and the BSA score. * P<0.05.
