Dot plot of fecal calprotectin levels in the different diagnostic groups. The cutoff value for normality (10 mg/L) is shown by the horizontal line. The calprotectin levels in all organic diagnostic groups except those with diabetic diarrhea differed significantly (P = to <0.0001) from those in the IBS group.
