How Sustained is Roux-en-Y Gastric Bypass Long-term Efficacy? : Roux-en-Y Gastric Bypass efficacy.
Observational study in Obesity surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 19 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
purposeThe rate of weight regain after Roux-en-Y Gastric Bypass (RYGB) can hamper the procedure long-term efficacy for obesity treatment and related comorbidities. To evaluate the rate of weight loss and comorbidity remission failure 10 years or more after RYGB surgery. MATERIALS AND
methodsRetrospective observational cohort study. Patients submitted to RYGB for obesity treatment at a single centre with 10 years or more after surgery underwent a clinical reassessment.
resultsAmong the subjects invited for clinical revaluation (n = 585), only those who performed RYGB and attended the hospital visit were included in the study (n = 281). The pre-operative mean body mass index (BMI) was 44.4 ± 6.1 kg/m
conclusionRYGB has a high rate of long-term successful weight loss and obesity-associated comorbidity improvement. Weight loss failure requiring revision surgery occurs in a small proportion of patients. Our data confirms the long-term effectiveness of RYGB as primary bariatric intervention.
