FIGURE 5.

Clinical parameters of pSS groups. The clinical characteristics of the patients were different in the groups. The severe group showed higher RF levels and damage (SSDDI) in comparison with the mild and moderate groups, meanwhile, the mild group presented the lower levels of RF but higher damage than the moderate group. Anti‐Ro/La levels were higher in the severe group but without significant difference (P = .065 and P = .070). Kruskal‐Wallis test with the Bonferroni correction was performed to analyzed groups. RF: Rheumatoid Factor, CRP: C Reactive Protein, SSDAI: Sjögren's Syndrome Disease Activity Index, SSDDI: Sjögren's Syndrome Disease Damage Index
