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

purposeDecreasing popularity of Roux-en-Y gastric bypass (RYGB) in bariatric-metabolic surgery may be due to higher perceived peri-operative complications. There are few studies on whether preoperative weight loss can reduce complications or reoperations following RYGB. We investigated this using a standardised operative technique. MATERIALS AND

methodsRetrospective single-centre study of RYGB from 2004 to 2019 using a prospective database. Preoperative behavioural management included intentional weight loss. Maximum preoperative weight, weight on the day of operation, and Obesity-Surgery Mortality Risk Score (OS-MRS) class were recorded. Short-term outcomes (post-operative stay, 30-day complication and reoperation rates) were analysed.

resultsIn 2,067 RYGB patients (1,901 primary and 166 revisional), median preoperative total body weight loss (TWL) was 6.2% (IQR: 2.5-10.7%). The median age was 46 (interquartile range (IQR) 38-54) and 80.4% were female (n=1,661). For primary surgery, the median body mass index (BMI) was 47.6 kg/m

conclusionsRYGB performed using a standardised technique has low overall risk. The influence of preoperative weight loss on outcomes was inconsistent.
