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

backgroundOverwhelming evidence shows that obesity is associated with brain structural alterations in young adults. However, the specific sex related changes in obesity and their associated with crystallized intelligence still remained unclear.

methodsIn this study, 243 young adults with obesity and matched 243 lean individuals were enrolled from the Human Connectome Project Release S1200 dataset. Surface-based morphometry approach was adopted to investigate altered brain structures and related sex difference in young adults with obesity with three structural indicators including cortical thickness (CT), cortical surface area (CSA), and subcortical gray matter volume (GMV).

resultsWhile in female young adults, no significant difference of GMV of right amygdala was observed between obesity and lean groups, in male young adults, obesity group exhibited significantly higher GVM of right amygdala than lean group. Then, obesity male young adults showed significant correlation between GMV of right amygdala and crystallized intelligence, and such significant correlation was not found in obesity female young adults.

conclusionsObesity male young adults showed significantly higher GMV of right amygdala than lean male young adults, which was further associated with crystallized intelligence. Such findings were not observed in obesity female young adults. These findings suggested that the sex difference of adverse effect of obesity may be associated with the alterations of GMV of right amygdala.
