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
backgroundChildren and adolescents with intellectual disability (ID) frequently experience various comorbid psychiatric symptoms. However, research on the comorbidity of psychiatric disorders in this population remains limited. In this study, we aimed to comprehensively examine the prevalence of psychiatric disorders among children and adolescents with ID in South Korea from 2012 to 2021.
methodsWe obtained data from the National Health Insurance Service-National Health Information Database (NHIS-NHID) on individuals aged 2-18 years who were diagnosed with ID (F70-F79.9) between 2012 and 2021. Psychiatric disorders were identified using the following the International Classification of Diseases, 10th Edition codes: attention-deficit/hyperactivity disorder (ADHD) (F90), autism spectrum disorder (ASD) (F84), language disorder (F80), tic disorders (F95), anxiety disorders (F401-F402, F410-F411, F930-F932), depressive disorder (F32, F33), conduct disorder (F918, F928, F911), and oppositional defiant disorder (ODD) (F913). We analyzed the annual prevalence of comorbid psychiatric disorders.
resultsThroughout the study period, males consistently outnumbered females (62.6-65.5% vs. 34.5-37.4%). ADHD had the highest prevalence among psychiatric disorders, increasing from 30.23% in 2012 to 41.77% in 2021. Similar increasing trends were observed for ASD (10.95-15.46%) and depression (10.46-19.37%). Significant sex differences were observed in most disorders: ADHD, ASD, tic disorders, language disorder, conduct disorder, and ODD showed male predominance (
conclusionThis study enhances our understanding of the epidemiology of psychiatric comorbidities in South Korean children and adolescents with ID. The evaluation of comorbid psychiatric disorders in this population is crucial for prognosis, with particular attention needed for ADHD and depressive disorder due to their relatively high prevalence. Future research should focus on preventing and treating psychiatric comorbidities in children and adolescents with ID.
