Examining the significance of age of onset in persons with lifetime anorexia nervosa: Comparing child, adolescent, and emerging adult onsets in nationally representative U.S. study.

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
objectiveThis study compared sociodemographic and clinical profiles of adult patients with lifetime DSM-5-defined anorexia nervosa (AN) categorized by age-of-onset using data from U.S. national sample of adults.
methodStudy included 216 participants from Third National Epidemiological Survey Alcohol and Related Conditions (NESARC-III) who met criteria for lifetime AN based on structured diagnostic interviews (AUDADIS-5) with age-of-onset prior to age 25. Of the 216 participants, 30 were categorized as child-onset (<15 years old), 104 adolescent-onset (15-18 years of age), and 82 "emerging-adult" (19-24 years of age); the three groups were compared on their clinical characteristics.
resultsAmong participants with lifetime diagnoses of AN with onsets earlier than 25 years, adjusted prevalence rates for the three groups were: 11.8% (SE = 2.04; child-onset), 39.6% (SE = 2.69; adolescent-onset), and 48.6% (SE = 2.67; emerging-adult). Child-onset group reported more frequent adverse childhood experiences (ACEs), lowest BMI, longest episode-duration, was least likely to attend college, and had highest rate of lifetime psychiatric comorbidity. Child-onset group had earliest age of help-seeking and were most likely to have been hospitalized. Group differences persisted in analyses adjusting for sociodemographic characteristics and duration of AN episode. DISCUSSION: Our findings, based on a nationally representative sample of U.S. adults with lifetime diagnoses of AN, suggest that those with child-onset had more severe AN, greater life difficulties, and greater lifetime psychiatric comorbidity. Findings emphasize the importance of earlier recognition and rapid referral to effective treatments.
