n/a: not applicable. ANA: antinuclear antibodies. ESR: Erythrocyte sedimentation rate. Results for quantitative variables are shown in Median with Interquartile Range, and Kruskal Wallis test was used to perform comparisons between groups. For quantitative variables measured only in two groups, Mann Whitney U test was used to perform comparisons between both groups. The qualitative variables are presented in frequencies, using Chi squared test to compare between groups. Mann Whitney U test was performed to compare between two groups as a post Hoc test, in which PR-SLE patients are older than Active SLE patients (p = 0.001), and older than the healthy subjects (p = 0.017). n/a: not applicable.
