Risk of Neuropsychiatric Disorders After Pediatric Delirium in Children Under 12: A Cohort Study.
Article in Psychiatry investigation, 2026. 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
objectiveDelirium is known to be related to neuropsychiatric comorbidities as long-term consequences in adult patients. However, the risk of major neuropsychiatric disorders after pediatric delirium remains largely unexplored.
methodsWe analyzed de-identified electronic health records (2013 to 2023) from the TriNetX Research network, a network with more than 111 million patients. Patients under age 12 years with delirium and a control group without delirium were identified and matched by age, sex, race, ethnicity, and physical comorbidities at a one-to-four ratio. We applied Cox regression and Kaplan-Meier analysis to assess the risk of neuropsychiatric disorders.
resultsA total of 618 pediatric patients with delirium were included, demonstrating a 2.15-fold higher risk of neuropsychiatric disorders than controls without delirium (hazard ratio [HR] with 95% confidence interval [CI]: 2.15, 1.82-2.56). The 5-year freedom from these disorders was 68.5% (95% CI, 65.5-71.8) in the study cohort, whereas it was 49.8% (95% CI, 44.1-56.2) in the control cohort. Subgroup analysis showed that children aged 6 years or younger were more likely to be diagnosed with externalizing disorder, including substance use disorder (HR=4.34; 95% CI, 2.00-9.44; p<0.001), intellectual disability (HR=1.71; 95% CI, 1.27-2.30; p<0.001), and attention-deficit/hyperactivity disorder (HR=2.25; 95% CI, 1.16-4.34; p=0.02).
conclusionPediatric patients with delirium are at increased risk of major neuropsychiatric disorders compared to their control counterparts without delirium. Clinicians need to be aware of early symptoms and signs suggesting major neuropsychiatric disorders during the long-term follow-up period.
