1 · What the graph read from 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.

2 · The registry

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

introductionThe optimal biliopancreatic limb (BPL) length in One Anastomosis Gastric Bypass (OAGB) remains debated, largely due to limited long-term outcome data. The primary objective of this study was to evaluate five-year results of weight loss, metabolic outcomes, and complication rates following OAGB with a fixed 150 cm BPL.

methodsThis retrospective study was conducted at a high-volume bariatric center within the National Health Service (NHS) in the United Kingdom. We reviewed patients who underwent OAGB with a fixed 150 cm BPL between December 2015 and June 2019. Perioperative care followed the standard bariatric protocol of our institution. Patients were followed at six-month intervals for two years, and again at five years post-operatively.

results274 patients were included, with a five-year follow-up rate of 73.7%. At two years, Mean %Excess Weight Loss (%EWL) was 77.0% (95% CI: 73.5-80.5) and Mean %Total Weight Loss (%TWL) was 35.0% (95% CI: 33.5-36.5). At five years, mean %EWL was 64.1% (95% CI: 60.7-67.5) and %TWL was 29.4% (95% CI: 27.9-30.9). Remission rates for type 2 diabetes, hypertension, and dyslipidemia were 55.8%, 32.2%, and 22.7%, respectively. The marginal ulcer rate was 4.5% (n = 9). Conversion to Roux-en-Y configuration (RYC) occurred in 5.9% (n = 12) of patients, and the malnutrition rate at five years was 0.5% (n = 1).

conclusionOAGB with a 150 cm BPL demonstrated effective outcomes with acceptable complication rates and a favorable balance between efficacy and safety, with a low incidence of severe malnutrition.
