Fig. 1From: Elevated levels of faecal calprotectin in primary Sjögren’s syndrome is common and associated with concomitant organic gastrointestinal diseaseElevated levels of faecal calprotectin in primary Sjögren’s syndrome. Faecal calprotectin levels were higher in patients with primary Sjögren’s syndrome (n = 56) than in healthy control subjects (n = 29) (p = 0.002 by Mann–Whitney U test). Subjects with a concomitant organic gastrointestinal (GI) disease are indicated by closed triangles; other subjects are represented by open circles Back to article page
