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

backgroundOne Anastomosis Gastric Bypass-Mini Gastric Bypass (OAGB-MGB) is rapidly gaining popularity and is currently being performed by an increasing number of bariatric surgeons worldwide. However, excessive postoperative weight loss and malnutrition still remain a major concern regarding this procedure. The aim of this observational retrospective study was to investigate whether a tailored biliopancreatic limb (BPL) length relative to small bowel length (SBL) is superior to a fixed BPL length of 200 cm in terms of weight loss results and nutritional deficiencies in morbidly obese patients 1 year following OAGB-MGB. MATERIALS AND

methodsSixty-four patients who underwent OAGB-MGB were divided into two consecutive groups depending on the BPL length used: fixed 200-cm BPL and tailored BPL groups. Anthropometric measurements (%EWL, TWL, %TWL) and nutritional parameters (vitamin A, vitamin D

resultsNo statistically significant differences were observed between the patients in two groups in terms of %EWL, TWL, %TWL. The number of patients with deficiencies of vitamin A (p = 0.030), vitamin D

conclusionTailoring BPL length by bypassing about 40% of the SBL seems to be safe and effective. According to preliminary results of this study, a tailored BPL length relative to SBL is even likely to be superior to the fixed 200-cm BPL as it is associated with less nutritional deficiencies while providing similar weight loss results. Further randomized studies with larger sample sizes and longer follow-up periods are necessary to confirm the primary results of this study.
