The Clinical Characterization of Blocking Tics in Patients With Tourette Syndrome.
Article in Journal of movement disorders, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveTourette syndrome (TS) is a neurodevelopmental disorder characterized by the presence of motor and phonic tics. Blocking phenomena, characterized by arrests in motor activity causing interruptions in movements or speech, have also been described in patients with TS. In this study, we aimed to characterize the frequency and features of blocking tics in patients with TS.
methodsWe studied a cohort of 201 patients with TS evaluated at our movement disorders clinic.
resultsWe identified 12 (6%) patients with blocking phenomena. Phonic tic intrusion causing speech arrest was the most common (n = 8, 4%), followed by sustained isometric muscle contractions arresting body movements (n = 4, 2%). The following variables were statistically related to blocking phenomena: shoulder tics, leg tics, copropraxia, dystonic tics, simple phonic tics, and number of phonic tics per patient (all p < 0.050). In the multivariate regression, the presence of dystonic tics (p = 0.014) and a higher number of phonic tics (p = 0.022) were associated with blocking phenomena.
conclusionBlocking phenomena are present in approximately 6% of patients with TS, and the presence of dystonic tics and a higher frequency and number of phonic tics increase the risk for these phenomena.
