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

Though theoretical accounts describe self-regulation as dynamic, empirical studies typically rely on static measures that fail to capture changes in self-regulation from day to day or moment to moment. As a result, little is known about how children's self-regulation may fluctuate within person, despite clear relevance for educators. In this article, we capitalized on repeated observations from wearable devices to test the idea that daily increases in activity across the school day could reflect a school-aged child's inability to regulate their physical activity to be appropriate to the school setting. In a national sample followed from birth to age 26 (
