The decline in physical activity among adolescent students: a cross-national comparison.

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
backgroundThe decline in physical activity during adolescence is a key public health concern. This comparative study assesses whether the age-related decline in physical activity among high school students occurs similarly in the United States (U.S.) and Ontario, whether the decline in physical activity is steady throughout the age range, or whether any declines are age-specific.
methodsData are based on self-reports of 9th- to 12th-graders derived from the 2001 Youth Risk Behavior Survey (n=13,503) and the 2001 Ontario Student Drug Use Survey (n=1322). Physical activity is measured by the number of days of vigorous physical activity during the past 7 days.
resultsIn both samples, there was a dominant and steady decline in physical activity between ages 14 and 18 years. The number of activity days was higher in the U.S. than in Ontario holding constant age and sex. However, a significant sample-by-age interaction showed that the decline in the percentage of U.S. students reporting 3 or more physical activity days was greater than it was in Ontario.
conclusionsWhile the pattern of decline was shown to be similar, the decline was stronger among US adolescents. Future research should examine additional factors influencing the decline in activity and the optimal timing of programs to reduce the decline.
