Childhood Disintegrative Disorder (CDD): Symptomatology of the Norwegian Patient Population and Parents' Experiences of Patient Regression.
Article in Journal of autism and developmental disorders, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Childhood Disintegrative Disorder (CDD) is a rare and little researched developmental disorder characterised by regression in language and social skills after a period of seemingly normal development until at least the age of 2 years. The study contacted all parents of CDD patients in Norway to assess patient symptomatology and parents' experiences of regression via questionnaire or interview. There were 12 participants. Symptomatology was in-line with previous studies, with universal regression in language and social skills and onset predominantly at 2-4 years. Regression was connected to feelings of 'loss' and uncertainty over the prognosis for CDD patients. The study supported CDD diagnostic criteria and showed that CDD patient regression has profound implications for parental well-being.
