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

BACKGROUND AND

aimsWe sought to assess the evolution of Crohn's disease behavior in an American population-based cohort.

methodsMedical records of all Olmsted County, Minnesota residents who were diagnosed with Crohn's disease from 1970 to 2004 were evaluated for their initial clinical phenotype, based on the Montreal Classification. The cumulative probabilities of developing structuring and/or penetrating complications were estimated using the Kaplan-Meier method. Proportional hazards regression was used to assess associations between baseline risk factors and changes in behavior.

resultsAmong 306 patients, 56.2% were diagnosed between the ages of 17 and 40 years. Disease extent was ileal in 45.1%, colonic in 32.0%, and ileocolonic in 18.6%. At baseline, 81.4% had nonstricturing nonpenetrating disease, 4.6% had stricturing disease, and 14.0% had penetrating disease. The cumulative risk of developing either complication was 18.6% at 90 days, 22.0% at 1 year, 33.7% at 5 years, and 50.8% at 20 years after diagnosis. Among 249 patients with nonstricturing, nonpenetrating disease at baseline, 66 changed their behavior after the first 90 days from diagnosis. Relative to colonic extent, ileal, ileocolonic, and upper GI extent were significantly associated with changes in behavior, whereas the association with perianal disease was barely significant.

conclusionsIn a population-based cohort study, 18.6% of patients with Crohn's disease experienced penetrating or stricturing complications within 90 days after diagnosis; 50% experienced intestinal complications 20 years after diagnosis. Factors associated with development of complications were the presence of ileal involvement and perianal disease.
