Associations of physical activity with phase angle in adolescents living with HIV: The moderating and mediating roles of physical fitness.
Article in Physiological reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
HIV infection and combination antiretroviral therapy (cART) can cause metabolic and cardiovascular changes in adolescents, who often have low physical activity (PA), harming their health. To investigate the relationship between PA levels and phase angle (PhA), we analyze potential moderating and mediating effects. Cross-sectional study with 47 adolescents (10-18 years) with vertically transmitted HIV. PA was assessed using PAQ-C; PhA was measured by tetrapolar bioelectrical impedance. Aerobic capacity was assessed by a submaximal bench step test, muscular strength by handgrip test, and body composition by anthropometric measures (arm muscle area [AMA] and body fat percentage [%BF]). Correlation, regression, and mediation and moderation analyses were performed. 61.7% showed inadequate PhA (<5.0°), mostly girls. A significant correlation existed between PA and PhA (r = 0.39; p = 0.01), maintained in adjusted regressions (β = 1.087; p = 0.001). General mediation and moderation effects were not confirmed; however, conditional analyses revealed high muscular strength significantly moderated the PA-PhA link (β = 1.0537; p = 0.0024). VO
