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
Aim: Sensory processing difficulties (SPDs) are common in pediatric obsessive-compulsive disorder (OCD), but their longitudinal course remains undercharacterized. This retrospective naturalistic observational study examined 25 children and adolescents with OCD, including eight with comorbid autism spectrum disorder (ASD), who received specialist outpatient care in Japan. Analyses according to ASD status were exploratory. Methods: The study was designed to characterize longitudinal changes in caregiver-rated SPDs rather than to evaluate treatment efficacy. Baseline and follow-up assessments included the Short Sensory Profile-Japanese version (SSP-J), Children's Yale-Brown Obsessive Compulsive Scale, and Children's Global Assessment Scale. Results: Caregiver-rated SPDs decreased over time, with a significant main effect of time on SSP-J scores ( Conclusion: In this sample, caregiver-rated SPDs decreased over time. Participants with ASD had higher SSP-J scores across assessment points, but the nonsignificant time × ASD interaction did not provide evidence of differential longitudinal change; ASD-related findings remain exploratory. Changes in SPDs were not significantly associated with changes in OCD severity or global functioning, and the clinical value of direct assessment of sensory difficulties requires further study.
