Precocious Puberty and Risk of Psychiatric Disorders: A Nationwide Cohort Study Using Prospective Registry Data.
Article in The Journal of clinical endocrinology and metabolism, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
contextEarly menarche within the general population has previously been linked to increased risk of mental health disorders, and such associations are likely to be even stronger in children diagnosed with extremely early puberty (precocious puberty); however, information is sparse.
objectiveInvestigate the association between precocious puberty and psychiatric disorders.
designA large cohort study included individuals in the National Danish Patient Registry with a diagnosis of precocious puberty from January 1, 1995, to December 31, 2020 (n = 9315, 11% boys), comprising patients registered with an ICD-10 diagnosis of central precocious puberty (n = 2955), unspecific premature puberty (n = 3948), premature thelarche (n = 937), and premature adrenarche (n = 1475). All cases were matched with 5 randomly selected referents from the background population (n = 46 566) according to age, sex, and calendar time (at diagnosis). Incident psychiatric disorders were identified in national health registries (average follow-up time of 7.9 years).
resultsPrecocious puberty (all cases) was associated with a statistically significant increased risk of attention-deficit/hyperactivity disorder (ADHD) (hazard ratio [HR]: 1.58; 95% CI: 1.36-1.84), anxiety (HR: 1.60; 95% CI: 1.48-1.74), autism (HR: 1.94; 95% CI: 1.67-2.25), depression (HR: 1.41; 95% CI: 1.29-1.53), eating disorders (HR: 1.23; 95% CI: 1.03-1.47), and schizophrenia (HR: 1.72; 95% CI: 1.40-2.10) compared to matched referents. Similar results were observed when stratified by sex, but with greatest effect size among boys. The associations were even stronger among individuals with central precocious puberty.
conclusionOur large register-based cohort study highlights a markedly increased risk of psychiatric disorders among individuals with precocious puberty.
