Physical health and fitness index in Chinese adolescents: a four-year cross-sectional study in Shandong Province.
Article in Frontiers in public health, 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
Introduction: To explore the relationship between physical health and physical fitness index (PFI) in adolescents aged 10 to 19 in Shandong Province. We aimed to offer evidence to support the local implementation of the Methods: Data were obtained from 51,764 adolescents aged 10 to 19 through the Shandong Student Physical Fitness and Health Surveys conducted in 2015, 2016, 2017, and 2020. Assessment of physical fitness included five core items: 50 running, sit and reach, standing long jump, 1,000 running/800 running, and pull-ups/sit-ups, which were then used to calculate the overall PFI. Body Mass Index (BMI) is defined according to the thresholds specified in t Results: Normal-weight individuals had the greatest fitness, and fitness declined in underweight and overweight groups. There was an inverted "U"-shaped curve relationship between BMI-Z and PFI. With comparable BMI, PFI changes was higher in females than males. The PFI and the prevalence of overweight/obese showed a consistent upward trend over the years. Conclusion: Females outperformed males in physical fitness, and fitness levels have improved over time. However, the prevalence of overweight/obese continues to rise, indicating a persistent imbalance between muscle and fat. This suggests that the region may be facing a "development-health paradox."
