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

Prevailing recommendations on reporting weight loss after bariatric and metabolic surgery are not evidence-based. They promote the outcome metric percentage excess weight loss (%EWL), sometimes indicated as percentage excess body mass index loss (%EBMIL). Many studies proved that this popular outcome measure, in contrast to other weight loss metrics, is inaccurate and error-sensitive when comparing weight loss within and between studies. It is inappropriate for assessing poor weight loss response and weight regain as well. The percentage (total) weight loss metric is the best alternative. The Dutch Society for Metabolic and Bariatric Surgery (DSMBS) recommends to stop using the %EWL (or %EBMIL) metric as primary outcome measure in all cases and calls on the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) to propagate this evidence-based recommendation.
