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 &

aimsWe conducted a systematic review with meta-analysis to estimate rates and trends of colectomy in patients with ulcerative colitis (UC), and of primary and re-resection in patients with Crohn's disease (CD), focusing on contemporary risks.

methodsThrough a systematic review until September 3, 2019, we identified population-based cohort studies that reported patient-level cumulative risk of surgery in patients with UC and CD. We evaluated overall and contemporary risk (after 2000) of surgery and analyzed time trends through mixed-effects meta-regression.

resultsIn patients with UC (26 studies), the overall 1-, 5-, and 10-year risks of colectomy was 4.0% (95% CI, 3.3-5.0), 8.8% (95% CI, 7.7-10.0), and 13.3% (95% CI, 11.3-15.5), respectively, with a decrease in risk over time (P < .001). Corresponding contemporary risks were 2.8% (95% CI, 2.0-3.9), 7.0% (95% CI, 5.7-8.6), and 9.6% (95% CI, 6.3-14.2), respectively. In patients with CD (22 studies), the overall 1-, 5-, and 10-year risk of surgery was 18.7% (95% CI, 15.0-23.0), 28.0% (95% CI, 24.0-32.4), and 39.5% (95% CI, 33.3-46.2), respectively, with a decrease in risk over time (P < .001). Corresponding contemporary risks were 12.3% (95% CI, 10.8-14.0), 18.0% (95% CI, 15.4-21.0), and 26.2% (95% CI, 23.4-29.4), respectively. In a meta-analysis of 8 studies in patients with CD with prior resection, the cumulative risk of a second resection at 5 and 10 years after the first resection was 17.7% (95% CI, 13.5-22.9) and 31.3% (95% CI, 24.1-39.6), respectively.

conclusionsPatient-level risks of surgery have decreased significantly over time, with a 5-year cumulative risk of surgery of 7.0% in UC and 18.0% in CD in contemporary cohorts. This decrease may be related to early detection and/or better treatment.
