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.

Abstract

backgroundLittle is known of the clinical outcome of patients with older-onset inflammatory bowel disease [IBD]. We performed a systematic review to determine phenotype and outcomes of older-onset IBD compared with younger-onset subjects.

methodsA systematic search of Embase and Medline up to June 2015 identified studies investigating phenotype and outcomes of older-onset [diagnosed at age ≥ 50 years] Crohn's disease [CD] and ulcerative colitis [UC] subjects. Pooled analyses of disease phenotype, medication use, and disease-related surgery were calculated.

resultsWe analysed findings from 43 studies comprising 8274 older-onset and 34641 younger-onset IBD subjects. Compared with younger-onset patients, older-onset CD patients were more likely to have colonic disease (odds ratio [OR] 2.56, 95% confidence interval [CI] 1.88 - 3.48) and inflammatory behaviour [OR 1.19, 95% CI 1.07 - 1.33], and less likely to have penetrating disease or perianal involvement. More older-onset UC patients had left-sided colitis [OR 1.49, 95% CI 1.18 - 1.88]. Although fewer older-onset IBD patients received immunomodulators [CD: OR 0.44; UC: OR 0.60] or biologicals [CD: OR 0.34; UC: OR 0.41], older-onset CD was similar in the need for surgery [OR 0.70, 95% CI 0.40 - 1.22] whereas more older-onset UC patients underwent surgery [OR 1.36, 95% CI 1.18 - 1.57].

conclusionsElderly IBD patients present with less complicated disease, but have similar or higher rates of surgery than non-elderly patients. Whether this reflects a non-benign disease course, physicians' reluctance to employ immunomodulators, or both, merits further study which is essential for improving the care of IBD in the elderly.
