21. In Guatemalan preschoolers, the median fecal calprotectin value was 58 mg/kg, with a mean of 98 +/- 136 mg/kg and a range from 10 to 950 mg/kg; 61% of values were above the manufacturer's cut-off for elevated concentration and 51% exceeded an age-adjusted criterion. The central tendency (mean or median) and distribution were generally shifted to the right in relation to comparable reports from children across the world. PMID: 27101538

24. Data support a role of S100A9 to initiate and amplify the neutrophilic inflammation in asthma, possibly via inducing IL-1beta, IL-17 and IFN-gamma. PMID: 28847516
25. The median faecal calprotectin level was similar in cases with abdominal pain-related functional gastrointestinal disorders (7.8 mug/g, 95% CI: 7.8-8.4) including those with gastritis, and controls (9.1 mug/g, 95% CI: 7.8-11.3). Faecal calprotectin is not a predictor of gastritis and is similar in children with functional abdominal pain symptoms and in controls. PMID: 26913755
