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

introductionLaparoscopic sleeve gastrectomy (LSG) is the most popular bariatric procedure performed worldwide. However, many patients undergo secondary surgery due to either weight-related and complication-related reasons or both. Conversional options vary with one-anastomosis gastric bypass (OAGB) and Roux-n-Y gastric bypass (RYGB) being the most common. The aim of the study was to assess the safety and efficacy of converting failed LSG to either OAGB or RYGB, and compare weight-related results and post-conversion complications.

methodsRetrospective review of hospital records of patients who underwent conversion from LSG to either RYGB or OAGB due to insufficient weight loss or weight regain in 7 bariatric centers between 2013 and 2019. Data retrieved included demographics, anthropometrics, comorbidities, indication for conversion, conversion type, complications, and weight loss.

resultsDuring the study period, 396 patients were included in the study. Eighty-four (21%) patients were lost to follow-up. RYGB and OAGB were performed in 119 and 144 patients, respectively. Mean age and body mass index (BMI) at revision were 44.2 years (range 19-72) and 40.6 ± 5.9 kg/m

conclusionsConversion of LSG to OAGB, compared to RYGB, results in increased weight loss but a higher rate of GERD and potential nutritional deficiencies.
