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

While fluid cognition (FC) demonstrates marked development from childhood to adulthood, less is known about the pace of nonlinear improvements in FC processes, whether FC maturation converges across processes, and how FC architecture varies with age. Participants (N = 1,049, 8-21 years, 50.52% female, 7.05% Asian, 0.29% American Indian/Alaska Native, 12.96% Black or African American, 0.19% Hawaiian or Pacific Islander, 61.11% White, 15.82% mixed race) completed FC tasks indexing inhibitory control, cognitive flexibility, processing speed, episodic memory, and working memory. Performance in all processes increased during childhood and early adolescence and grouped into Cognitive Control and Memory sub-architectures. Although this organization appeared in childhood, Cognitive Control and Memory became more distinct with age.
