- The Mann–Whitney U-test was used to evaluate markers scored semiquantitatively, and the χ2 test was used to evaluate markers scored as present or absent. Results are expressed as median (range), and markers evaluated as present or absent are expressed as percentage of positive results. P < 0.05 was considered statistically significant. PsA, psoriatic arthritis.
