Correlation Between Gastrojejunal Anastomosis Diameter, Distensibility Index, and Weight Regain After Roux-en-Y Gastric Bypass.
Article in Obesity surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
introductionGastrojejunal anastomosis (GJA) dilation is an independent predictor of weight regain (WR) after Roux-en-Y gastric bypass (RYGB). However, the role of planimetric measurements in this context remains unknown.
methodsThis is a retrospective cohort study including adult RYGB patients who underwent a diagnostic endoscopy with Endoflip assessment of the GJA. We excluded patients in the early postoperative period and those with abnormal endoscopic findings (marginal ulcers and gastro-gastric fistulas).
resultsThirty-four patients were initially included. Endoscopic GJA diameter had a moderate positive correlation with WR (r=+0.438, p=0.011). However, after excluding the 7 patients with GJA> 30 mm, there was no significant correlation. There was a moderate agreement between the EndoFLIP-GJA diameter at 60mL and endoscopic diameter (ICC=0.576, p=0.049). The distensibility index (DI) showed a consistent moderate negative correlation with WR. Considering the maximum DI at 40 ml, we found a cutoff of DI = 7 mm
conclusionVisual estimation of the GJA diameter correlates with EndoFLIP at 60mL. In the subset of patients with GJA ≤ 30 mm, more distensible GJAs are associated with lower rates of WR. Larger studies are needed to confirm this correlation and to validate its utility for clinical management.
