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
This study aimed to examined whether multidimensional callous-unemotional (CU) traits and conduct problems (CP) yield distinct latent profiles in a clinically referred sample of youth, and if these profiles differ on externalizing symptoms, aggression, irritability, and CU-related impairment. Participants were 290 clinically referred youth (57.9% male) aged 8–16 years (M = 10.40, SD = 2.33) and primarily identified as White (85.9%). Diagnoses included ADHD (90.7%), ODD (35.3%), and CD (3.5%). Mothers completed the Inventory of Callous-Unemotional Traits, Disruptive Behavior Disorders Rating Scale, Nova Scotia Modified IOWA Conners, Affective Reactivity Index, the Callous-Unemotional Problems and Impairment scale, Screen for Child Anxiety Related Disorders, and Short Mood and Feelings Questionnaire. Latent profile analysis was conducted using four ICU facets and a CP score to derive subtypes. A four-profile solution emerged: High CU/CP (16.2%), Emotionally Detached (32.8%), Low CU/CP (35.9%), and Remorseless–Callous (15.2%). Profiles differed significantly on CU and CP indicators (partial η² = 0.15). High CU/CP and Remorseless–Callous groups showed elevated ODD and CD diagnoses, proactive/reactive aggression, irritability, depression, and CU impairment compared to Emotionally Detached and Low CU/CP profiles. The High CU/CP class exhibited the highest slow dissipation of aggression, whereas the Remorseless–Callous class had greater relational aggression. The Emotionally Detached group had lower rates of anxiety. Multidimensional CU trait analysis revealed clinically distinct subtypes, including a novel Emotionally Detached profile. These findings underscore heterogeneity in CU presentations and highlight the need for tailored assessment and intervention. Future research should evaluate the stability and treatment responsiveness of these profiles.
