FC faecal calprotectin, pSS primary Sjögren’s syndrome

Values are given as medians in millimetres, and higher values indicate less symptoms. Mann–Whitney U test was used to compare groups. Significant differences were identified between control subjects in comparison with both pSS groups. No significant differences were identified between patients with pSS with and without pathological FC testing

^a p < 0.05 compared with control subjects
