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
objectiveThough disruptive, impulse-control, and conduct disorders (DICCD) represent significant public health challenges in Korea, diagnosis-specific epidemiological data remain limited. This study investigated DICCD's prevalence, risk factors, and psychiatric comorbidities as distinct diagnostic entities in a nationally representative sample of Korean children and adolescents.
methodsData from the National Mental Health Survey of Korea-Child & Adolescent 2022 (6,275 participants aged 6-17 years) were analyzed. Diagnoses were made using the Korean version of the Kiddie Schedule for Affective Disorders and Schizophrenia-Computerized Version, based on Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Sociodemographic and parental characteristics, lifestyle variables, and psychiatric comorbidities were assessed. Multivariable logistic regression analyses identified risk factors and comorbidity patterns.
resultsPrevalence rates were 2.76% for DICCD, 2.52% for oppositional defiant disorder (ODD), and 0.61% for conduct disorder (CD). ODD and CD shared risk factors-adolescent age (15-17 years), parental anxiety, and child sleep problems-but also exhibited distinct risk factor profiles. ODD was associated with parental depression, maternal employment, and excessive screen use, and CD with male sex and rural residence. Comorbidity patterns also differed. ODD was associated with mood disorders. CD exhibited elevated risks for substance use disorders and suicidal behavior.
conclusionThis first nationally representative study demonstrated distinct prevalence rates and risk factors for DICCD, ODD, and CD in Korean children and adolescents. Disorder-specific comorbidity patterns require tailored prevention and treatment approaches. The findings underscore the clinical importance of maintaining diagnostic distinctions and implementing comprehensive psychiatric screening protocols for high-risk adolescents.
