Comparison of marginal ulcer rates between antecolic and retrocolic laparoscopic Roux-en-Y gastric bypass.
Article in Obesity surgery, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05799105 (OPEN Versus InTact Capsule Proton Pump Inhibitors for the Treatment of Marginal Ulcers After Bariatric Surgery), which is not on this map. Cited by 12 papers.
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.

Abstract
introductionMarginal ulcer can be a serious complication after laparoscopic gastric bypass surgery. The aim of this study was to compare the rates of marginal ulcer between the antecolic and the retrocolic technique, in a large cohort of patients. PATIENTS AND
methodsOver a near 10-year period, 1,142 patients underwent laparoscopic gastric bypass surgery. The antecolic and the retrocolic technique were used in respectively 572 and 570 consecutive patients. All procedures were performed using a circular stapled gastrojejunostomy.
resultsPatients were followed for 18 to 99 months (mean 48.8 months). During follow-up, 46 patients developed a marginal ulcer (4 %), 32 in the antecolic group (5.6 %) and 14 in the retrocolic group (2.5 %). Nineteen patients (3.3 %) in the antecolic group and eight patients in the retrocolic group (1.4 %) developed early marginal ulcer (i.e., within 3 months after surgery). The mean time to onset of anastomotic ulcer symptoms after surgery was 11 months (range 0.25-72). Forty-four patients were submitted to medical treatment, and 35 patients (79.5 %) had complete resolution of their symptoms.
conclusionPatients with an antecolic Roux limb develop significantly more marginal ulcers (p = 0.007) and early marginal ulcer (p = 0.033) than the patients with a retrocolic Roux limb. The antecolic technique seems to be a risk factor for appearance of marginal ulcer.
