Verification and concentration of elevated proteins in PsA synovial fluid (Set II) by selected reaction monitoring assays, normalized against heavy-labeled peptides. Symbols represent SF samples from individual subjects; horizontal lines depict the mean, and vertical lines the standard deviation. ****Indicates P < 0.0001; ***P < 0.001; **P < 0.01; *P < 0.05; ns: non-significant.
