Factors Associated with Weight Loss After Endoscopic Transoral Outlet Reduction (TORe).
Article in Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
introductionEndoscopic transoral outlet reduction (TORe) has emerged as a safe and effective treatment option for weight regain after Roux-en-Y Gastric Bypass (RYGB). Factors that predict successful weight loss after TORe are incompletely understood. The aims of this study were to evaluate procedural factors and patient factors that may affect percent total body weight loss (%TBWL) after TORe.
methodsA retrospective cohort study was performed on patients after TORe. The primary outcomes were %TBWL at 6 and 12 months based on four procedural factors: purse-string (PS) vs. non-purse-string (NPS) suture pattern, gastric pouch sutures (N), change in the diameter of the gastrojejunal anastomosis, and change in the length of the gastric pouch. Secondary outcomes included patient factors that affected weight loss.
resultsFifty-one patients underwent TORe. Weight loss for completers was 11.3 ± 7.6% and 12.2 ± 9.2% at 6 and 12 months. There was a correlation between %TBWL and change in pouch length at 6 and 12 months and number of sutures in the pouch at 6 months. The difference in %TBWL between PS and NPS groups at 6 months (PS, n=21, 12.3 ± 8.5% and NPS, n=8, 8.7 ± 3.7%) and 12 months (PS, n=21, 13.5 ± 9.2% and NPS, n=5, 7.0 ± 7.9%) did not reach statistical significance. For secondary outcomes, depression was associated with %TBWL.
conclusionChange in pouch length and number of sutures in the pouch correlated positively while depression correlated negatively with weight loss after TORe. Further studies are needed to understand these effects.
