From: Serum proteome analysis identifies a potential biomarker for axial psoriatic arthritis
Unbiased L-MS/MS-based protein analysis. a PCA score plot of the serum samples of the discovery cohort. b PLS-DA score plot of the serum samples of the discovery cohort. c This Venn diagram shows the number of DEPs found in the pairwise comparison among the three groups. d The volcano plot shows the DEPs between axPsA and pPsA. PEDF was the top-upregulated DEP according to the p-value. axPsA axial psoriatic arthritis, pPsA peripheral psoriatic arthritis, HC healthy control, DEPs differentially expressed proteins, PEDF pigment epithelium-derived factor
