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

objectiveThis study sought to explore the relationships between sex hormones and obesity-related markers, while utilizing Mendelian randomization (MR) to evaluate their causal links.

methodsData from 5179 participants of the 2013-2016 National Health and Nutrition Examination Survey (NHANES) were analyzed. Multivariate linear regression and generalized additive models were utilized to examine linear and non-linear associations between sex hormones and obesity-related parameters. Causal inference was explored via a two-sample MR analysis, with inverse-variance weighting (IVW) as the primary approach.

resultsCross-sectional assessments showed that in males, testosterone levels, SHBG, and T/E2 ratio were negatively correlated with obesity, while estradiol displayed a non-linear, inverted U-shaped relationship. In females, estradiol and SHBG had negative associations with adiposity measures. MR analysis revealed that genetically increased Bio-T was associated with lower obesity risk in males, while SHBG showed a negative correlation with visceral and waist obesity. In females, Bio-T and FAI were associated with higher visceral adipose tissue volume and waist circumference, findings consistent with potential causal effects.

conclusionsSex hormones show sex-specific associations with obesity. Testosterone is protective against obesity in males, whereas female hyperandrogenism elevates the risk of obesity, particularly central obesity. These results offer novel perspectives for obesity-related health interventions.
