Portomesenteric vein thrombosis after laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass: a 36-case series.
Review in Surgical endoscopy, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers, 1 of them a synthesis 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
backgroundPortomesenteric vein thrombosis following laparoscopic bariatric surgical procedures is a serious and potentially lethal complication. It is quite rare, and its clinical presentation, management, and sequelae remain poorly understood.
methodsWe searched PubMed, Medline, Google Scholar, Ovid, and Cochrane databases for articles reporting case series and systematic reviews in the English language on patients who underwent laparoscopic bariatric surgery and had a subsequent portal or mesenteric vein thrombosis. Articles discussing laparoscopic gastric banding were excluded.
resultsA total of 14 articles reporting on 36 cases were found. We analyzed the pooled data from these case reports and series with emphasis on number of reported patients, demographics, time of diagnosis, risk factors, symptoms, management, complications, and sequelae.
conclusionsPortomesenteric vein thrombosis is not uncommon following laparoscopic bariatric surgery and appears to occur more after laparoscopic sleeve gastrectomy. Bariatric surgeons should have a high index of suspicion for early detection and treatment of this potentially lethal complication. Obese patients at high risk for venous thrombosis should be screened for genetic predisposition for hypercoagulable state and should be considered for extended thromboprophylaxis postoperatively.
