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

backgroundWe evaluated long-term incidence and identified risk factors of colectomy in pre-biologics and biologics eras for treatment of ulcerative colitis.

methodsAfter IRB approval, using data obtained from the Régie d'assurance maladie du Québec, we defined two cohorts: pre-biologics (1998-2004) and biologics (2005-2011) eras. Patients with inflammatory bowel disease or colectomy 1 year prior to first diagnosis of ulcerative colitis were excluded. Multivariate logistic regression model compared patient baseline characteristics. Kaplan-Meier curves displayed unadjusted time to event. Cox proportional hazards models were used to compare adjusted colectomy and mortality rates, respectively.

resultsIn pre-biologics and biologics eras, 335/2829 and 314/3313 patients, respectively, underwent colectomy. Median follow-up (first and third quartiles) was similar (p = 0.206). Incidence rates for colectomy were 36.08/1000 and 29.99/1000 patient years. Unadjusted rate of colectomy was higher in pre-biologics era (p = 0.004). Predictors of colectomy included anemia (1.66; 1.38-2.01), gastrointestinal hospitalizations (1.24; 1.04-1.47), congestive heart failure (2.08; 1.27-3.40), and male gender (1.47; 1.26-1.72). Mortality was 8.06 and 3.18% in pre-biologics and biologics eras. After adjusting for potential confounders, age (1.08; 1.05-1.12) and urgent colectomy (5.65; 2.19-14.54) remained associated with increased mortality hazard.

conclusionIncidence of colectomy decreased after introduction of biologics. Risk factors for colectomy were gastrointestinal hospitalizations, anemia, male gender, and congestive heart failure. Emergent surgery and age were predictors of mortality.
