Moderating effect of selenium intake on the association between obesity and sex hormone levels in children and adolescents: NHANES 2013-2016.
Article in Asia Pacific journal of clinical nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND AND
objectivesThis study aimed to evaluate the role of selenium intake on the correlation between obesity and sex hormone levels in children and adolescents. METHODS AND STUDY
designChildren and adolescents (6-19-year-old) with complete body mass index (BMI), selenium intake, and sex hormone level data were included. Applying weighted linear regression model to analyze the relationships of obesity and se-lenium intake with testosterone, estradiol, and sex hormone-binding globulin (SHBG) levels. Then, interaction terms for different selenium intake levels (<Q1, ≥Q1) and obesity (no, yes) were constructed, to investi-gate the moderating effect of selenium intake on the correlation between obesity and sex hormones.
resultsA total of 3,380 participants were enrolled. Although selenium intake showed no direct relationship with tes-tosterone, estradiol, or SHBG levels in any group (p > 0.05), it demonstrated a significant interaction with obesity in terms of sex hormone levels. In females aged less than 12 years, there was an interaction between obesity and selenium intake on testosterone levels (pinteraction = 0.007). The interaction of obesity and selenium intake on SHBG levels was observed in both males and females (all pinteraction <0.001). Moreover, a trend was observed for the effects of these interaction terms on testosterone, estradiol and SHBG levels (all ptrend <0.05).
conclusionsSelenium intake may play a moderating effect in the relationship between obesity and sex hor-mones.
