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

objectiveThe objective of this study was to investigate underlying mechanisms of long-term effective weight loss after laparoscopic sleeve gastrectomy (LSG) and effects on the medial orbitofrontal cortex (mOFC) and cognition.

methodsA total of 18 individuals with obesity (BMI ≥ 30 kg/m

resultsNo significant improvement in general cognition was found after LSG. Decreases in gray matter volume of the bilateral mOFC and increases in RSFC of the right mOFC were observed 12 months after LSG. Weight loss was associated with RSFC, general cognitive scores, and triglyceride changes. Multivariate linear regression model revealed gray matter volume of the left mOFC and working memory scores at baseline explained 55.2% of the variation in weight loss.

conclusionsThese findings suggest that mOFC imaging and cognitive scores could serve as biomarkers for predicting persistent weight loss after LSG, which provides a solid foundation for a potential target for neuromodulation research.
