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
objectivesIndividuals with both avoidant/restrictive food intake disorder (ARFID) and pediatric acute-onset neuropsychiatric syndrome (PANS) report restrictive eating. Inflammatory and immunological alterations may drive the onset of restrictive eating and comorbid obsessive-compulsive (OC) symptoms in PANS, while the etiology of restrictive eating in ARFID is unknown. Nevertheless, few studies have explored PANS and related OC symptoms among individuals with ARFID. We aimed to identify the frequency and nature of PANS and OC symptoms among those with full or subthreshold ARFID. We also explored associations between OC severity, ARFID profiles, and infection history.
methodsThe study included 37 adolescents and young adults with subthreshold or full ARFID. We quantified the frequency of PANS/pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection symptoms and diagnoses, as well as OC symptoms and severity, in our ARFID sample. We analyzed associations between ARFID profiles and OC severity, along with the relationship between infection history and OC severity.
resultsTwo individuals (5%) met PANS criteria, and 17 (46%) reported lifetime mild-severe OC severity. The fear of aversive consequences profile was associated with a significant increase in log-transformed OC severity (β = 1.2, DISCUSSION: In the first study to examine PANS and related symptoms among individuals with ARFID, we demonstrated salient overlap between PANS, OC symptoms, and ARFID. Further research is needed to examine the relationship between ARFID and PANS.
