Mesenteric Defect Closure and the Rate of Internal Hernia in Laparoscopic Roux-en-Y Gastric Bypass: A Systematic Review and Meta-analysis.
Synthesis in Obesity surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 21 papers, 2 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
Internal hernias are a worrying complication from laparoscopic Roux-en-Y gastric bypass (LRGB), with potential small bowel necrosis and obstruction. An electronic database search of Medline, Embase, and Pubmed was performed. All studies investigating the internal hernia rates in patients whose mesenteric defects were closed vs. not closed during LRGB were analysed. Odds ratios were calculated to assess the difference in internal hernia rate. A total of 14 studies totalling 20,553 patients undergoing LRGB were included. Internal hernia rate (220/12,445 (2%) closure vs. 509/8108 (6%) non-closure) and re-operation for small bowel obstruction (86/5437 (2%) closed vs. 300/3132 (10%) non-closure) were reduced when defects were closed. There was no difference observed when sutures were used to close the defects compared to clips/staples.
