Demographic and Genetic Predictors of ADHD Diagnoses and Medications in Electronic Health Records.
Article in Research square, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: The rise in stimulant prescriptions, which are commonly prescribed for attention-deficit/hyperactivity disorder (ADHD), has raised concerns due to their high potential for abuse. Methods: This study utilized data from the Penn Medicine BioBank (PMBB) to investigate prescription stimulant use by identifying: (1) individuals with an International Classification of Diseases (ICD) code for ADHD, (2) individuals prescribed a stimulant, (3) individuals with both an ICD code for ADHD and a stimulant prescription, (4) individuals without an ICD code for ADHD but with a stimulant prescription, and (5) a control group. We assessed differences in demographics, medication type, and dosages amongst these groups. For participants with available genetic data, we calculated polygenic scores (PGS) for ADHD and used regression models to examine whether PGS for ADHD is associated with ADHD diagnosis and stimulant medication use. Results: Demographic differences between the five groups were identified. Individuals with an ADHD diagnosis were more likely to be younger, female, and White, compared to the control group. Individuals with ICD codes for ADHD were prescribed significantly higher average doses of stimulants compared to those without ADHD. PGS for ADHD was significantly associated with the likelihood of receiving an ADHD diagnosis, using a stimulant, using a stimulant in the absence of an ADHD diagnosis, and receiving a lower dosage of a stimulant. Conclusions: Findings from this research will contribute to discussions surrounding the role of genetic predisposition and demographic disparities in ADHD diagnosis and treatment.
