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

aimsTo investigate the macro- and microstructural changes of bone in patients with inflammatory bowel disease [IBD] and to define the factors associated with bone loss in IBD.

methodsA total of 148 subjects, 59 with Crohn's disease [CD], 39 with ulcerative colitis [UC], and 50 healthy controls were assessed for the geometric, volumetric and microstructural properties of bone using high-resolution peripheral quantitative computed tomography. In addition, demographic and disease-specific characteristics of IBD patients were recorded.

resultsIBD patients and controls were comparable in age, sex, and body mass index. Total [p = 0.001], cortical [p < 0.001], and trabecular volumetric bone mineral density [BMD] [p = 0.03] were significantly reduced in IBD patients compared with healthy controls. Geometric and microstructural analysis revealed significantly lower cortical area [p = 0.001] and cortical thickness [p < 0.001] without differences in cortical porosity, pore volume, or pore diameter. CD showed a more severe bone phenotype than UC: cortical bone loss was observed in both diseases, but CD additionally showed profound trabecular bone loss with reduced trabecular BMD [p = 0.008], bone volume [p = 0.008], and trabecular thickness [p = 0.009]. Multivariate regression models identified the diagnosis of CD, female sex, lower body mass index, and the lack of remission as factors independently associated with bone loss in IBD.

conclusionIBD patients develop significant cortical bone loss, impairing bone strength. Trabecular bone loss is limited to CD patients, who exhibit a more severe bone phenotype compared with UC patients.
