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
Objectives: Inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS) are increasingly prevalent disorders. Faecal calprotectin is useful in the differential diagnosis of IBD from IBS and monitoring IBD activity. We verified the Bühlmann fCAL turbo faecal calprotectin assay on the Binding Site, Optilite benchtop analyser. Design: Accuracy, precision, lower limit of quantitation (LLoQ), and linearity of the Bühlmann fCAL turbo faecal calprotectin assay on the Binding Site, Optilite benchtop analyser were ascertained. Comparison with the Bühlmann Quantum Blue fCAL extended and DiaSorin, Liaison calprotectin assays were also undertaken. Difference between assays was evaluated using the Wilcoxon signed-rank test and method comparison was undertaken using Spearman's rank correlation (rs), difference plots and Passing-Bablok regression analyses. Results: The fCAL turbo assay was linear between 25 and 10,000 μg/g, and the LLoQ was 25 μg/g. Intra-, and inter-assay imprecision was <5%. There was a good agreement (rs = 0.96) and no significant bias (3%, p = 0.10) present between the fCAL turbo and Quantum Blue extended assays. Between the fCAL turbo and DiaSorin, liaison assays there was a good agreement (rs = 0.97), but a significant bias (53%, p = <0.01) was present. Conclusions: The fCAL turbo assay performs well on the Binding Site, Optilite benchtop analyser. Calprotectin results are commutable between with Bühlmann fCAL turbo and Quantum Blue fCAL extended assays, but not between Bühlmann and DiaSorin calprotectin assays.
