Anastomotic Strictures After Roux-en-Y Gastric Bypass: a Cohort Study from the Scandinavian Obesity Surgery Registry.
Article in Obesity surgery, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 26 papers, 4 of them syntheses that pooled 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.
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
backgroundRoux-en-Y gastric bypass (RYGB) is the most common bariatric procedure worldwide. Anastomotic stricture is a known complication of RYGB. The aim was to explore the incidence and outcomes of strictures within the Scandinavian Obesity Surgery Registry (SOReg).
methodSOReg included prospective data from 36,362 patients undergoing bariatric surgery in the years 2007-2013. Outcomes were recorded at 30-day and at 1-year follow-up according to the standard SOReg routine. The medical charts of patients suffering from stricture after RYGB were requested and assessed.
settingNational bariatric surgery registry
resultsAnastomotic stricture within 1 year of surgery was confirmed in 101 patients representing an incidence of 0.3%. Risk factors for stricture were patient age above 60 years (odds ratio (OR), 6.2 95% confidence interval (CI) 2.7-14.3), circular stapled gastrojejunostomy (OR 2.7, 95% CI 1.4-5.5), postoperative anastomotic leak (OR 8.9 95%, CI 4.7-17.0), and marginal ulcer (OR 30.0, 95% CI 19.2-47.0). Seventy-five percent of the strictures were diagnosed within 70 days of surgery. Two dilatations or less was sufficient to successfully treat 50% of patients. Ten pecent of patients developed perforation during dilatation, and the risk of perforating at each dilatation was 3.8%. Perforation required surgery in six cases but there was no mortality. Strictures in SOReg may be underreported, which could explain the low incidence in the study.
conclusionMost strictures present within 2 months and are successfully treated with two dilatations or less. Dilating a strictured gastrojejunostomy entails a risk of perforation (3.8%).
