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

backgroundChildren with autism spectrum disorder (ASD) frequently exhibit restrictive eating behaviors that may meet the criteria for avoidant/restrictive food intake disorder (ARFID). This disorder is characterized not only by behavioral disturbances but also by somatic impairments and functional complications. Timely identification of ARFID allows for therapeutic and nutritional interventions aimed at restoring fully balanced nutrition in order to achieve the highest possible level of development and health for every child with ASD. Despite high prevalence of avoidant/restrictive eating behaviors in children, the associated adverse health outcomes, and the frequency of clinical encounters, ARFID is often underdiagnosed and inadequately addressed within both psychiatric and pediatric care settings, highlighting the need for a multidisciplinary diagnostic approach.

aimTo develop and implement a multidisciplinary approach to the diagnosis of ARFID in children with ASD.

methodsA multistage mixed-methods design was applied to address the aim of the study. In the first stage, diagnostic criteria for ARFID were clustered. In the second stage, a conventional algorithm for examining patients with ASD to diagnose ARFID was developed. This was followed by a cross-sectional study, during which a comprehensive examination of patients with ASD was performed and approaches to the diagnosis of ARFID in children with autism were developed.

resultsA behavioral pattern of selective/restrictive food intake was identified in 71 (88.8%) children with autism out of 80. Somatic disorders (deviation of body weight from the norm, carbohydrate and/or lipid metabolism disorders, vitamin deficiencies, anemia) were observed in 66 (82.5%) children, and functional impairment - in 11 (19.7%). This defines an additional criterion necessary for diagnosing ARFID as a comorbid disorder and for implementing therapeutic interventions aimed at treating the identified pathology and restoring a balanced diet.

conclusionThis study proposes the identification of three diagnostic clusters of ARFID: behavioral, somatic, and functional impairment. These findings highlight the importance of a multidisciplinary approach and the need to assess somatic consequences when diagnosing ARFID and developing individualized treatment strategies.
