Unique Behavior Profiles That Specify Mental Distress in Autism.
Article in Journal of autism and developmental disorders, 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
purposePatients with autism spectrum disorder (ASD), particularly those with limited speech, may not communicate internal distress. Clinicians therefore often infer distress from observable aberrant behaviors, whose clinical significance may differ from that in typically developing (TD) individuals. We identified aberrant behavior profiles (ABPs) that differentially track symptom dimensions across ASD and TD groups, and between minimally verbal ASD (MV-ASD) and fluently verbal ASD (FV-ASD).
methodsWe pooled three NIMH Data Archive studies with CASI-5 severities (12 domains) and Aberrant Behavior Checklist (ABC) items (58 behaviors). After adjusting for age and sex, we applied Differentially Supervised Varimax to derive ABPs and tested group differences with permutation testing and false discovery rate control.
resultsIn ASD, a disruptive/hyperactive ABP related more strongly than in TD to ADHD-hyperactive and oppositional defiant severity and to generalized anxiety, social anxiety, and specific phobia. Emotional reactivity aligned with obsessions, somatization, and depressive severity, whereas withdrawal/self-injury aligned with social and separation anxiety. Preoccupation aligned with schizophrenia-related severity, whereas hypoactivity/depressed mood aligned with post-traumatic stress and specific phobia; in MV-ASD, passive withdrawal/hypoactivity related more strongly to obsessions, somatization, and depressive severity.
conclusionClinicians can use ABPs to guide next steps: match a patient's predominant behavior pattern to an ABP, then prioritize targeted history, caregiver probing, and symptom measures in the linked domains. For example, prominent withdrawal with self-injury should trigger focused screening for social and separation anxiety, whereas marked emotional reactivity should trigger assessment for obsessive symptoms, somatic distress, and depression.
