1 · What the graph read from it

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.

2 · The registry

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

backgroundEngaging in moderate-to-vigorous physical activity (MVPA) in early childhood can have both immediate and long-term health benefits. Strategies for consistently supporting this are currently unknown, largely due to the vast number of potentially interrelated and dynamic contributing factors that may also be heterogenous across children.

methodsWe developed an agent-based model (ABM) that represents children ages 3-9 who can engage in MVPA in a variety of settings in which they spend time. Our model incorporates key theoretical constructs identified in the literature and is grounded in high-quality empirical evidence, primarily participant data from a cohort-based randomized controlled trial with extensive longitudinal accelerometry measurement. We assess the ABM's ability to reproduce patterns of MVPA observed in the cohort.

resultsWe uncovered a specific model representation of key pathways and settings involved in MVPA for this age group that can closely reproduce real-world MVPA across multiple

conclusionsIn addition to immediate insights, this article provides proof of principle for a powerful tool that can further explore the etiology of childhood MVPA and inform practices and policies to positively affect early childhood PA, setting the stage for lifelong health.
