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
Excessive visceral adipose tissue (VAT) has proven to be an efficient predictor of cardiovascular disease (CVD), independent of body mass index (BMI) or total body fat, and reducing visceral obesity is key to addressing the current epidemic of CVD. Selenium (Se) is suggested to protect against CVD, but a direct link between dietary Se intake and VAT levels is lacking. This study investigated this relationship, emphasizing the importance of expressing Se intake relative to body weight. A total of 3244 individuals participated in the Complex Diseases in the Newfoundland population: Environment and Genetics (CODING) study. Dietary Se intake was assessed using the Willett food frequency questionnaire (FFQ). VAT mass and VAT volume were precisely measured via dual-energy X-ray absorptiometry (DXA). Visceral adiposity, as indicated by VAT mass and VAT volume, decreased significantly across increasing quartiles of dietary Se intake (µg/kg/d) in both sexes. Compared with participants in the lowest quartile, those in the highest quartile had substantially lower visceral adiposity with reduction of 50.97% in women, and 63.75% in men, respectively. Likewise, this inverse dose-dependent manner was also observed when dietary Se intake was expressed as µg/d. Moreover, a linear negative correlation between dietary Se intake (µg/kg/d) and visceral adiposity was discovered, whereas no significant correlation was found if dietary Se intake was expressed as µg/d. After controlling for possible confounders, the linear regression analyses revealed that a 10% increase in dietary Se intake (µg/kg/d) was associated with 2.73% decrease in visceral adiposity. Interestingly, this inverse correlation remained consistent across different sex, age and menopausal status subgroups, with greater associations observed in males, individuals younger than 35 years old, and women in menopausal status. This is the first study to demonstrate a significant inverse association between dietary Se intake and VAT, which is exclusively evident when intake is expressed relative to body weight (µg/kg/d). This finding resolves prior inconsistencies and suggests that ensuring adequate weight-adjusted Se intake could be a valuable nutritional strategy for reducing visceral obesity and improving CVD prevention.
