Long-term Follow-up 15 Years After Duodenal Switch or Gastric Bypass for Super Obesity: a Randomized Controlled Trial.
Trial report in Obesity surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 papers, 3 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
backgroundIn super obesity, Roux-en-Y gastric bypass (RYGB) may be insufficient why some surgeons advocate biliopancreatic diversion with duodenal switch (BPD/DS), a more malabsorptive procedure. There is a paucity of evidence regarding results beyond 10 years, especially after BPD/DS. The aim of this randomized controlled trial was to compare the long-term outcome of BPD/DS, and RYGB in patients with super obesity, i.e., body mass index (BMI) > 50 kg/m
methodsThis is a 13- to 17-year follow-up study of a single-center, single-blinded randomized trial in which 47 patients (BMI > 48 and eligible for bariatric surgery) were randomized 1:1 to BPD/DS and RYGB (25 men, 24 BPD/DS, 39.1 ± 9.9 years, BMI 54.5 ± 6.1 kg/m TRIAL REGISTRATION NUMBER: ISRCTN10940791.
resultsThirty-four (18 BPD/DS) of the living 42 patients (81.0%) participated. BPD/DS resulted in higher BMI loss (20.4 ± 7.9 vs. 12.4 ± 8.6, p = .008) and higher percent of total body weight loss (37.5% ± 12.2 vs. 22.8% ± 14.8, p = .004). BPD/DS was associated with lower fasting glucose, glycated hemoglobin (HbA1c), and low-density lipoprotein (LDL) as well as lower hemoglobin. Adverse events were more common after BPD/DS (2.7 vs. 0.9 per patient, p = .004). The global assessment tool BAROS (Bariatric Analysis and Reporting Outcome System) demonstrated superior scores for BPD/DS (p = .047).
conclusionWhen compared to RYGB, BPD/DS results in superior weight loss and metabolic control as well as superior BAROS score, however, at the cost of more adverse events.
