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.

Abstract

backgroundOne anastomosis (mini) gastric bypass (OAGB) is believed to be more malabsorptive than Roux-en-Y gastric bypass. A number of patients undergoing this procedure suffer from severe protein-calorie malnutrition requiring revisional surgery. The purpose of this study was to find the magnitude of severe protein-calorie malnutrition requiring revisional surgery after OAGB and any potential relationship with biliopancreatic limb (BPL) length.

methodsA questionnaire-based survey was carried out on the surgeons performing OAGB. Data were further corroborated with the published scientific literature.

resultsA total of 118 surgeons from thirty countries reported experience with 47,364 OAGB procedures. Overall, 0.37% (138/36,952) of patients needed revisional surgery for malnutrition. The highest percentage of 0.51% (120/23,277) was recorded with formulae using >200 cm of BPL for some patients, and lowest rate of 0% was seen with 150 cm BPL. These data were corroborated by published scientific literature, which has a record of 50 (0.56%) patients needing surgical revision for severe malnutrition after OAGB.

conclusionsA very small number of OAGB patients need surgical correction for severe protein-calorie malnutrition. Highest rates of 0.6% were seen in the hands of surgeons using BPL length of >250 cm for some of their patients, and the lowest rate of 0% was seen with BPL of 150 cm. Future studies are needed to examine the efficacy of a standardised BPL length of 150 cm with OAGB.
