The Importance of the Microbiome in Bariatric Surgery: a Systematic Review.
Synthesis in Obesity surgery, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 29 papers, 2 of them syntheses that pooled 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.
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
Bariatric surgery results in sustained weight loss, improvement of metabolic and hormonal changes, and reduction of comorbidities in obese patients. However, beneficial effects of bariatric surgery are not solely explained by restriction and malabsorption induced by surgery itself. Changes in the microbiome might play a role in this mechanism. A systematic review was performed in which 21 studies were included. The microbiome was affected by surgery and profound changes occurred in the first year of follow-up. An increase in Bacteroides and Proteobacteria and a decrease in Firmicutes were observed postoperatively in most studies. These changes were associated with weight loss. Bariatric surgery induces profound changes in the microbiome. This may be related to the beneficial effect of bariatric surgery on comorbidities associated with obesity.
