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

backgroundAngelman syndrome (AS) is a rare, neurological genetic disorder for which no clinical outcomes assessments (COAs) or conceptual models (CM) have been developed.

objectiveThis study aimed to identify symptoms and impacts relevant and important in this patient population and develop a conceptual model of AS, and to evaluate the content validity of selected COA instruments with potential for inclusion in clinical studies of AS to capture treatment benefit.

methodsFor both concept elicitation (CE) and cognitive interviews (CI), caregivers of children, adolescents, and adults with AS and clinicians with AS experience were targeted. For CI, clinicians discussed the Modified Performance-Oriented Mobility Assessment (MPOMA-G) and ProtoKinetics Zeno Walkway™ and caregivers reviewed the Pediatric Evaluation of Disability Inventory Computer Adaptive Test (PEDI-CAT), the Anxiety, Depression and Mood Scale (ADAMS), the Aberrant Behavior Checklist-Community (ABC-C), and the Morning Diary.

resultsFour clinicians and 34 caregivers participated in CE interviews; three clinicians and 36 caregivers participated in CI. A conceptual model, initially informed by literature, was refined based on interview data. Five domains of symptoms, signs, and characteristics of AS were identified: cognitive and executive functioning, social-emotional, emotional-expressive behavior, sensory-compulsive behavior, and physical. Patient impacts were identified in three domains: activities of daily living, school, and social/community. Caregiver impacts were identified in five domains: mental health, physical health, work, home, and social. While all instruments demonstrated the ability to provide relevant data for the AS population, each instrument either contained some items irrelevant to individuals with AS or was missing important concepts based on the interviews. No single instrument covered all relevant domains specific to AS.

conclusionFuture work should consider the adaptation of existing COAs and the development of a novel AS-specific instrument for use in clinical research to ensure outcomes important to this patient population are captured.
