Table 2 Descriptive analysis of the psoriatic arthritis magnetic resonance imaging score (PsAMRIS) and sub-score values overall and at the MCP, PIP, and DIP joints 2–5 in PsA patients. For each item, the mean ± standard deviation is presented. Differences between joint levels were assessed for significance using one-way ANOVA. p values < 0.05 were considered significant and are given in bold
