Associations of sex, age and adiposity in endothelium-independent dilation in children.

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
objectiveTo examine the association of age, sex, and obesity status on endothelial-independent dilation (EID) among children and adolescents. STUDY
designThis study examined 264 children (143 males) between 8 to 18 years old (mean ± SD: age = 14.3 ± 2.7 years). Endothelial-independent dilation was assessed via ultrasound imaging of the brachial artery following administration of 0.3 milligrams of sublingual nitroglycerin. A one-way analysis of variance with Bonferroni post hoc comparisons assessed sex-differences in percent peak EID dilation (EID%-peak) and EID area under the curve (EID%-AUC), while analysis of covariance (ANCOVA) adjusted for race, age, body mass index percentile (BMI-percentile), and brachial artery diameter. Multiple linear regression evaluated the association of sex, age, BMI-percentile, percent body fat (%BF), and brachial artery diameter on EID.
resultsPrior to adjustment, EID%-peak was significantly higher among females than males (mean ± SE: 26.9 ± 0.5% versus 22.9 ± 0.6%, p < 0.001, respectively); similar findings for EID%-AUC (4214% ± 105%·s versus 3398% ± 97%·s, p < 0.001) were observed. After adjusting for covariates, EID%-AUC remained consistent (p = 0.03) while EID%-peak was not significantly different between sexes (p = 0.21). EID%-peak was significantly higher among normal weight compared to obese participants (p = 0.04), while no differences were observed between obesity status after adjustment for brachial artery diameter (p = 0.64). Both unadjusted (p = 0.16) and adjusted EID%-AUC (p = 0.24) was not significantly different between obesity status. BMI-percentile was not associated with EID%-peak (p = 0.76) or EID%-AUC (p = 0.30). Additionally, %BF was not associated with EID%-peak (p = 0.56) or EID%-AUC (p = 0.15). After adjusting for brachial artery diameter, BMI-percentile, and age, males had lower EID%-AUC (p = 0.03) and lower but not significant EID%-peak (p = 0.21). SIGNIFICANCE: Vascular smooth muscle function was significantly lower among male children and adolescents, which is suggestive that impaired EID and increased cardiovascular disease risk among males may begin in childhood. Interestingly, obesity status and BMI-percentile was not associated with EID in children and adolescents after adjusting for brachial artery diameter.
