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

Introduction: The National Institutes of Health Toolbox for Assessment of Neurological and Behavioral Function Cognition Battery (NIHTB-CB) is a brief neuropsychological battery for the assessment of crystalized (i.e., vocabulary and word reading) and fluid cognition (i.e., working memory, visual episodic memory, processing speed, and executive functions). This study examined the frequency of low NIHTB-CB scores and proposes flexible algorithms for identifying cognitive weaknesses and impairment among youth. Methods: Participants were 1,269 youth from the NIHTB-CB normative sample who did not have a neurodevelopmental, psychiatric, or medical problem that might be associated with cognitive difficulties (53% boys and 47% girls; M = 11.8 years-old, SD = 3.0, range 7-17). The sample included the following racial and ethnic composition: 58.1% White, 17.8% Black or African American, 16.8% Hispanic, 1.7% Asian, 3.1% multiracial and ethnic identities, and 2.6% not provided. The frequency of obtaining low scores falling at or below several cutoffs were calculated and stratified by gender, age, and crystalized intellectual ability. Results: Considering the five fluid tests, nearly two-thirds of children and adolescents obtained one or more scores ≤ 25th percentile, half obtained one or more scores ≤ 16th percentile, between a third and a fourth obtained one or more scores ≤ 9th percentile, and nearly a fifth obtained one or more scores ≤ 5th percentile. We propose flexible, psychometrically derived criteria for identifying a cognitive weakness or impairment. Discussion: Referencing the base rates of low scores will help researchers and clinicians enhance the interpretation of NIHTB-CB performance among children with cognitive weakness or impairments that are neurodevelopmental or acquired.
