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

aimsCrohn's disease is a debilitating chronic inflammatory disorder of the mammalian gastrointestinal tract. Current interventions using anti-tumour necrosis factor [anti-TNF] biologics show long-term benefit in only half of patients. This study focused on the role of the TNF receptor 1 [TNFR1] in pathogenesis in a TNF-driven model of ileitis.

methodsWe studied TNFΔAU-rich element [ARE]/+ [TNFdARE] mice, which develop progressive ileitis similar to Crohn's ileitis. Histopathological analysis and gene expression profiling were used to characterize disease progression from 5 to 16 weeks. Mice with TNFR1 hemizygosity [TNFdARE/R1het] allowed us to assess gene dosage effects. Transcriptional profiling established inflection points in disease progression; inflammatory gene expression increased at 8 weeks with a plateau by 10 weeks, so these were selected as endpoints of treatment using the TNF biologic infliximab and the TNFR1-specific XPro1595. Differences in recruitment of cells in the lamina propria were assessed using flow cytometry.

resultsTNFdARE/R1het mice displayed stable long-term protection from disease, associated with decreased recruitment of CD11bhiF4/80lo monocytes and CD11bhiLy6Ghi neutrophils, suggesting an important role of TNFR1 signalling in pathogenesis, and indicating potential benefit from TNFR1-specific intervention. Treatment with infliximab and XPro1595 both showed a similar impact on disease in TNFdARE mice. Importantly, these beneficial effects were greatly surpassed by hemizygosity at the TNFR1 locus.

conclusionsTreatment with either infliximab or XPro1595 produced moderate protection from ileitis in TNFdARE mice. However, hemizygosity at the TNFR1 locus in TNFdARE mice showed far better protection, implicating TNFR1 signalling as a key mediator of TNF-driven disease.
