Trends of incident adult Attention-deficit/hyperactivity disorder diagnoses before, during and after the pandemic provincial state of emergency in British Columbia (2013-2023): a population-based study.
Article in Lancet regional health. Americas, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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: Emerging evidence indicates a potential rise in attention-deficit/hyperactivity disorder (ADHD) incidence worldwide and in British Columbia (BC) since the pandemic. Given the high comorbidity of ADHD with substance use disorder (SUD) and other mental disorders, understanding changes in ADHD diagnosis among adults is crucial for healthcare planning amid BC's drug poisoning (overdose) crisis. We aimed to report how rates of newly diagnosed adult ADHD changed before, during and after the pandemic by demographic variables and histories of SUD or mental disorders. Methods: We conducted interrupted time series analyses on overall and stratified monthly incidence rates of ADHD diagnosis between Jan, 2013, and Nov, 2023 in BC, using data from linked population-based administrative databases. Findings: The pre-pandemic average of newly diagnosed adult ADHD was 8.8 cases per 100,000 population monthly. During the pandemic (Mar, 2020-Jun, 2021), this rose to 19.2 driven by a 4.9% (95% confidence interval: [3.7, 6.2]) month-over-month increase. When the pandemic ended, the monthly rate jumped by 107.3% [68.5, 155.0] in Jul, 2021 and grew 1.5% [0.4, 2.7] per month thereafter, averaging 34.8 cases per 100,000 post-pandemic. Substantial differences in trends emerged when stratified by sex and SUD histories. Interpretation: This exponential rise in adult ADHD may be explained by pandemic-related sociocultural changes and the broader societal evolution in mental health awareness in recent years and decades. This rise could foreshadow a potential increase in the population at risk of SUD, underscoring the urgent need for bidirectional integration of ADHD and SUD services. Funding: We acknowledge the UBC Psychiatry Stimulus Grants Initiative.
