Psychometric properties of the Psychopathology in Autism Checklist (PAC).
Article in International journal of developmental disabilities, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
Psychiatric disorders in individuals with co-occurring autism spectrum disorders (ASD) and intellectual disability (ID) are common, but diagnosis presents many challenges. The Psychopathology in Autism checklist (PAC) is among the very few instruments specifically developed for this group of individuals. The psychometric properties of the PAC (i.e. criterion validity, specificity, sensitivity and predictive values) were explored by comparing scores with assessments on the Aberrant Behavior Checklist (ABC) and examining how well assessment by the PAC at referral predicts final clinical diagnoses. Results indicated a significant correlation with the ABC, further supporting the validity of the PAC. Sensitivity and Specificity for specific diagnoses were variable, although positive predictive value for "any diagnosis' was relatively high. The study confirms the potential value of the PAC as a screening checklist but highlights the need for clinical diagnosis to be based on a multimodal, multidisciplinary assessment.
