Door-to-door Video-Enhanced Prevalence Study of Tourette Disorder Among African Americans.
Article in Evidence-based practice in child and adolescent mental health, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
Tourette syndrome (TS) affects about 0.5% of the population worldwide, but only sparse and conflicting data exist on TS prevalence among minority samples. Here we used VISIT-TS (a survey preceded by a short video showing tic phenomenology) and community outreach to provide estimates of tic disorder prevalence in African Americans. Community health workers (CHWs) left flyers at households in a predominantly minority neighborhood and approached people at a community health fair. Of 606 such contacts, 222 individuals agreed to discuss the study. Of these, 70% enrolled, of whom 82% identified as Black and 64% female. The VISIT-TS was well received. Lifetime prevalence of TS or another chronic tic disorder (TS/CTD) was 3.2%, and 31% endorsed any lifetime simple tic. The number of enrolled Black participants is remarkable compared to earlier TS studies, allowing one of the first prevalence estimates in this population (TS 2.3%, TS/CTD 3.9%). Tic disorders were endorsed only by Black respondents, though the small White sample precluded statistical comparison. Women had higher rates than men of TS (M:F = 0:1) and of any lifetime simple tic (M:F = 0.85), differing significantly from the expected 4:1 ratio (
