A prospective single centre pilot evaluation of a serum calprotectin assay in unselected GI patients.
Trial report in Clinical biochemistry, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundWhilst C-reactive protein (CRP) is an established serum marker of inflammation, its use in gastroenterology has been limited by its poor sensitivity and specificity for GI disease. Faecal calprotectin (FC) has been adopted into mainstream GI practice as a sensitive but non-specific marker of intestinal inflammation. However, stool samples collection for FC can be challenging and the possibility of utilising a sensitive and specific serum biomarker of intestinal inflammation in luminal gastroenterology is an attractive prospect. This work investigates the performance of serum calprotectin (SC) compared to current biomarkers, FC and CRP, in an unselected cohort of patients attending our GI unit.
methodsPatients attending in and outpatients within an adult GI service who submitted a stool sample for FC analysis were identified. A total of 109 who had a serum sample obtained within one day of stool sample collection had the serum analysed for CRP and SC and the correlation between these biomarkers was investigated.
resultsThe intraclass correlation coefficient (ICC) between SC, FC and CRP was 0.10, 95% CI -0.09-0.28 and 0.18, 95% CI -0.01-0.35, respectively. The ICC between FC and CRP was 0.18, 95% CI -0.01-0.35.
conclusionsOur data reveals that there is no significant correlation between SC and FC, nor between SC and CRP in a large unselected cohort of GI patients. Therefore, as a serum biomarker for intestinal inflammation, SC is unlikely to be of clinical utility and the search for an appropriate serum GI biomarker continues.
