Early developmental milestones associated with tics and psychopathological comorbidity: An EMTICS study.
Observational study in European child & adolescent psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundChronic Tic disorders (CTD) including Tourette Syndrome (TS), are associated with psychopathological comorbidities. Attention deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD) and other comorbidities have been linked to delays in early developmental milestones. Few studies have investigated the relationship between early developmental milestones, tic severity, and related comorbidities.
methods383 participants aged 3-16 years (76.8%, n = 294 boys) with CTD from the baseline assessment of the European Multicenter Tics in Children Study (EMTICS), were evaluated for: retrospective early developmental milestones (sitting, walking, first words, complete a sentence, bladder and bowel control), tic severity, tic-related functional impairment, obsessive-compulsive disorder (OCD), ADHD, oppositional defiant disorder (ODD) and suspected ASD. Data was collected using gold-standard self and clinician reporting instruments. Analyses included Pearson correlations and logistic regressions.
resultsCorrelations between the acquisition of developmental milestones and tic severity or impairment were significant with small effect sizes (severity of motor tics and tic impairment were correlated with walking (r = .11), while vocal tics were correlated with first words (r = .12)). Logistic regression revealed that delayed acquisition of first words was significantly associated with ADHD, ODD and suspected ASD (Odds Ratio (ROR): 1-1.13, 1.04-1.22, 1.05-1.21, respectively), while delayed walking acquisition was associated with OCD (ROR: 1.01-1.27). DISCUSSION: This study highlights the association between early developmental milestones and later psychopathological comorbidities in CTD patients. These findings emphasize the need for further research to distinguish between children with only tics and those with tics and psychopathological comorbidities, to improve early detection of individuals at risk.
