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

This systematic review evaluated the role and measurement of total small bowel length (TSBL) in metabolic bariatric surgery (MBS) following PRISMA guidelines. Twenty-seven studies involving 6968 adult patients undergoing bariatric surgery with TSBL measurement were included. Outcomes of interest included TSBL, weight loss outcomes, comorbidities improvement/resolution, and the relationship between TSBL and weight loss outcomes. Mean TSBL ranged from 506.5 cm to 795.0 cm. Complications related to TSBL measurement occurred in six patients (0.2%), all small bowel perforations. Nutritional deficiencies ranged from 0.3% to 33.8%. In six studies, tailoring procedures according to TSBL was associated with fewer nutritional deficiencies than in controls. Adoption of standardized TSBL measurement protocol may have a notable impact on surgical outcomes with respect to reducing malabsorptive complications in highly malabsorptive procedures.
