Genetic associations with temporal trends in physical activity and body mass index across four decades: the population-based HUNT study, Norway.

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
abstractObjectives: To examine whether genetic liability to physical activity is associated with temporal trends in physical activity and body mass index over the past four decades. Methods: The Trøndelag Health Study (HUNT) is a population-based longitudinal study conducted in 1984-1986, 1995-1997, 2006-2008 and 2017-2019. Leisure-time physical activity and body mass index were assessed at all four surveys, and biological samples were obtained for genotyping since the second survey. We used linear mixed models to estimate the mean difference in minutes per week of leisure-time physical activity and body mass index (kg/m Results: In 1984-1986, participants in the fifth versus the first quintile of the PRS for physical activity reported 10.7 min/week (95% CI, 8.1 to 13.3) more leisure-time physical activity. Three decades later, in 2017-2019, the corresponding difference was 21.4 min/week (95% CI, 19.2 to 23.7), indicating interacting effects between calendar time and genetic liability to physical activity (p Conclusions: This study shows increasing differences in both leisure-time physical activity and body mass index over the past four decades between people with high versus low genetic liability to physical activity.
