Table 3 Faecal calprotectin is stable over time in systemic sclerosis

From: Faecal levels of calprotectin in systemic sclerosis are stable over time and are higher compared to primary Sjögren’s syndrome and rheumatoid arthritis

  Typical FC level  
Variability of FC over time Normal Elevated Substantially elevated All patients, n (%)

  1. aAll FC measures fall into the same category; ball FC measures fall into the same category except 1 that is 1 step lower/higher; cthe FC measures show higher variability than above. Stool samples were delivered for analysis of FC at three (Cohort A) or four (Cohort B) time points and FC was categorised as solida, stableb or inconclusivec. FC: faecal calprotectin measured in μg/g.
