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

objectiveExtraintestinal manifestations (EIMs) are common in paediatric inflammatory bowel disease (IBD), often impairing quality of life. Our aim was to assess whether EIMs at diagnosis are associated with disease severity in paediatric IBD.

methodsWe conducted a post hoc analysis from the Hungarian Pediatric IBD Registry (2010-2020), including children with Crohn's disease (CD) or ulcerative colitis (UC). Outcomes (relapse, steroid dependency, biological therapy (BT), surgery) were compared between patients with EIMs at diagnosis and those without, using Kaplan-Meier and Cox regression analyses.

resultsAmong 1590 patients, EIMs were more frequent in CD than in UC (25% vs 14%, p<0.0001). In CD, EIMs were linked to earlier steroid dependency (p=0.0047) and BT initiation (p=0.00049). Patients without EIMs had a higher risk of intestinal resection (HR 3.2; 95% CI 1.572 to 6.472; p=0.001). In UC, EIMs were not associated with relapse (p=0.600), steroid dependency (p=0.890) or need for BT (p=0.081). Colectomy occurred earlier in the patients with EIMs (p=0.032).

conclusionIn patients with CD, EIM at diagnosis more often required BT, but underwent fewer surgeries. In patients with UC, EIMs at diagnosis appeared to be associated with an increased risk of BT and colectomy.
