Figure 3. Multivariate data analysis and permutation test of psoriasis in varying degrees of severity.

(A) PLS-DA scores plots, (B) OPLS-DA, (C) Permutation test of PLS-DA, (D) Permutation test of OPLS-DA (● mild PV patients, ● moderate to severe PV patients, ● HC). The severity of psoriasis is defined by PASI score, PASI ≦10 being considered mild, PASI >10 being considered moderate to severe, compared with the healthy control, statistical pattern recognition results were shown.
