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

purposeOne-anastomosis gastric bypass (OAGB) has raised concerns about nutritional complications possibly attributed to the biliopancreatic limb (BPL) length. We aimed to assess the results of a conservative approach of OAGB compared with the original OAGB and Roux-en-Y gastric bypass (RYGB) in a 1-year follow-up study. MATERIALS AND

methodsThis retrospective study was conducted based on prospectively maintained data in a cohort of patients who underwent either RYGB with a Roux limb of a 150 cm and a BPL of 50 cm (n = 145), OAGB with a 200-cm BPL (n = 272), or OAGB with a 160-cm BPL (n = 383), from March 2013 to 2017 at three university hospitals by a single surgical team.

resultsGroups were comparable regarding age and sex. Mean preoperative body mass indexes of the RYGB, OAGB-160, and OAGB-200 groups were 44.5 ± 5.8, 45.6 ± 6.3, and 46.7 ± 6.4 kg/m

conclusionAfter 1 year, OAGB with a 160-cm BPL was as effective as OAGB with a 200-cm BPL and RYGB, but safer than OAGB-200. This approach also avoided the need for revisional surgery following postoperative malnutrition.
