The Influence of Different Alimentary and Biliopancreatic Limb Lengths in Gastric Bypass Patients.
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 10 papers, 4 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
purposeThe aim of this study was to compare the effect of two different limb lengths after RYGB on weight loss, postoperative gastro-intestinal complications, and vitamin deficiencies. MATERIALS AND
methodsA retrospective analyses of 100 patients after RYGB with 2 different limb lengths were done. Group A (50 patients) had a biliopancreatic limb (BPL) of 75 cm and an alimentary limb (AL) of 150 cm. Group B (50 patients) had a BPL of 150 cm and an AL of 75 cm. The effect on weight loss, body mass index, excess weight loss (EWL), total weight loss (TWL), and postoperative complications was analyzed up to 2 years postoperatively.
resultsPatients with a longer BPL achieved significantly more %EWL compared to a shorter BPL 2 years postoperatively (82.8 ± 31.2 versus 93.8 ± 15.1; p = 0.038). A significant difference was also seen in %TWL after 1 year (30.3 ± 10.1 versus 37.4 ± 6.9; p < 0.01) and 2 years (31.6 ± 7.5 versus 35.6 ± 8.6; p = 0.022), both in favor of group B. However, patients with a longer BPL (group B) showed significant more diarrhea and steatorrhea compared to group A (p < 0.01).
conclusionBPL of 150 cm is associated with more %EWL and %TWL 2 years after RYGB. However, it is accompanied by an increase of diarrhea and steatorrhea to disadvantage off group B. Future studies need to focus on further tailoring BPL and AL lengths to achieve the best possible outcomes for patients with morbid obesity.
