1 · What the graph read from it

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.

2 · The registry

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

Background and Aims: Although increasing evidence suggests a role for fungi in inflammatory bowel disease [IBD], data are scarce and mostly from adults. Our aim was to define the characteristics of fungal microbiota in newly diagnosed treatment-naïve children with Crohn's disease [CD]. Methods: The children referred for colonoscopy were prospectively enrolled in the study at King Khalid University Hospital, King Saud University, and Al Mofarreh Polyclinics in Riyadh. Tissue and stool samples were collected and frozen till sequencing analysis. The children with confirmed CD diagnosis were designated as cases and the others as non- IBD controls; 78 samples were collected from 35 children [15 CD and 20 controls]. Statistical analysis was performed to investigate CD associations and diversity. Results: CD-associated fungi varied with the level of phylogenetic tree. There was no significant difference in abundance between normal and inflamed mucosa. Significantly abundant CD-associated taxa included Psathyrellaceae [p = 0.01], Cortinariaceae [p = 0.04], Psathyrella [p = 0.003], and Gymnopilus [p = 0.03]. Monilinia was significantly depleted [p = 0.03], whereas other depleted taxa, although not statistically significant, included Leotiomycetes [p = 0.06], Helotiales [p = 0.08], and Sclerotiniaceae [p = 0.07]. There was no significant difference in fungal diversity between CD and controls. Conclusions: We report highly significant fungal dysbiosis in newly diagnosed treatment-naïve CD children. Depleted and more abundant taxa suggest anti-inflammatory and pro-inflamatory potentials, respectively. Further studies with larger sample size and including functional analysis are needed to clarify the significance of the fungal community in the pathogenesis of CD.
