The Role of Gastrojejunostomy Size on Gastric Bypass Weight Loss.
Article in Obesity surgery, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 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
backgroundThe laparoscopic Roux-en-Y gastric bypass (LRYGB) has been considered a reference procedure in the bariatric surgery. The linear-stapled gastrojejunostomy (GJ) has proved to be safe and effective, but its optimal size referred to postoperative weight loss remains poorly understood.
objectivesEvaluate the role of the linear-stapled GJ size in the mid-term post-LRYGB weight loss and occurrence of complications. MATERIALS AND
methodsFrom January to April 2014, 128 patients underwent LRYGB with linear-stapled GJ in a 2-year follow-up. The LRYGB were carried out with the same technical steps, except for the length of the GJ. In GJ-15-mm group (n = 64), the GJ was constructed with white 45-mm cartridge in an extension of only 15 mm whereas in GJ-45-mm group (n = 64), the GJ was achieved using full extension of the cartridge. The body mass index (BMI) reduction was recorded for 24 months after procedure.
resultsThe mean ages were 38 ± 10.6 and 41.3 ± 12.3 years, and there were 45 (70.3%) and 51 (79.7%) females in the GJ-15-mm and GJ-45-mm groups, respectively. The analysis on raw BMI data showed that both groups had significant reduction of BMI over time (p ≤ 0.05); however, reduction was greater in the GJ-15-mm group from 18 months onwards (p ≤ 0.05). The only complication observed was a case (1.56%) of stenosis in the group GJ-15 mm.
conclusionThe global analysis of BMI reduction indicated that the narrower GJ used (GJ-15-mm group) represented a favoring factor decreasing significantly more the BMI when compared to the wider one (GJ-45-mm group).
