1 · What the graph read from 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.

2 · The registry

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

backgroundThe Angelman Syndrome Video Assessment (ASVA) is a clinician-reported outcome measure that was developed to assess the functional ability of individuals with Angelman Syndrome (AS) in a familiar environment. Through standardized tasks and associated scorecards, clinicians assess four meaningful domains of functioning: communication, activities of daily living (ADLs, which include fine motor skills), gross motor, and external direction (i.e., the ability to follow directions) via scorecards with pre-established criteria. The aim of this project was to develop and refine the scorecards using a rigorous process in partnership with caregivers, clinicians, and researchers in the AS community.

methodsThe Scorecard development process included four phases: (1) video source material study, (2) identification of initial scoring criteria, (3) scorecard drafts, and (4) two (Caregiver and Clinician panel and PT panel) two-round modified Delphi processes to reach consensus. All phases were conducted remotely except for Round 2 of the Caregiver and Clinician Delphi Panel, which was conducted in person. Votes were held for each scoring criterion and consensus was defined as ≥ 70% agreement.

resultsIn the communication, ADLs, and external direction domains, scorecard criteria reached 80 to 100% agreement among caregivers (n = 8) and clinicians (n = 2), resulting in a total of 218 scoring criteria and levels across 10 tasks. In the gross motor domain, scorecard criteria reached 100% agreement among physical therapists (n = 8) with a total of 347 scoring criteria and levels across 8 tasks.

conclusionsThe ASVA was developed with insights from the AS community, including caregivers of individuals with AS, clinicians, and researchers. The ASVA is a novel, disease-specific, clinician-reported outcome measure that uses standardized video capture and scorecards that were developed through a rigorous process, resulting in well-developed criteria to quantify meaningful changes of function in individuals with AS in communication, ADLs, gross motor function, and external direction.
