Long-Term Outcome of Proximal Versus Very-Very Long Limb Roux-en-Y Gastric Bypass: the Roux-Limb to Common Channel Ratio Determines the Long-Term Weight Loss.
Article in Obesity surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe influence of the Roux limb (RL) length on weight loss in Roux-en-Y (RYGB)-type gastric bypass procedures is still unclear. This study analyzes the true impact of RL length by comparing the long-term outcomes of proximal RYGB (PRYGB) and very-very long limb RYGB (VVLL-RYGB).
methodsRL length in PRYGB was 150 cm. In VVLL-RYGB, common channel length was 100 cm. In both groups, biliopancreatic limbs measured 50-60 cm, resulting in equal total alimentary limb lengths. To adjust for pre-operative differences between groups, and to predict the long-term outcome, a mixed model analysis was performed.
resultsTwo hundred thirty-two patients with VVLL-RYGB (73.7% female, mean age 41.1 ± 10 years, initial BMI 45.8 ± 6.3 kg/m
conclusionThe VVLL-RYGB has a significantly higher long-term BMI reduction and a significantly lower weight rebound. The length of the Roux limb significantly influences long-term outcome.
