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

backgroundBile reflux (BR) is an issue after one anastomosis gastric bypass (OAGB). Cholecystectomy can increase BR in patients without a history of metabolic and bariatric surgery. We aimed to evaluate the effect of cholecystectomy on BR after OAGB.

methodsThis prospective observational study was conducted between March 2017 and December 2022 including 34 matched adult individuals with a body mass index ≥ 40 kg/m

resultsThirty-four patients were included in this study. BR into the esophagus was not detected in both groups. BR to the gastric pouch was observed in 4 patients (23.5%) of the OAGB group and 6 patients (35.3%) of the OAGB + LC group (P = 0.452). BR to gastric remnant was observed in 6 patients (one and five patients in OAGB and OAGB + LC groups respectively) (P = 0.072). There was no statistically significant difference between the two groups, although it was clinically significant.

conclusionCholecystectomy after OAGB is not associated with a change in the rate of BR in the gastric pouch but increases the incidence of BR into gastric remnant that may be harmful in the long term.
