1 · What the graph read from 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.

2 · The registry

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) is the most common cause of tics. Tics are classified as motor and phonic tics. The latter (previously also referred to as "vocal tics") are manifested by simple sounds (simple phonic tics) or complex, often semantically meaningful utterances (complex phonic tics).

methodsWe compared the clinical and demographic features of consecutive patients with TS who exhibited simple and complex phonic tics.

resultsThere were 149 patients, 117 (78.5%) of whom were males; the mean age at evaluation was 19.61 ± 12.97 years. In total, 35 (23.5%) of these manifested complex phonic tics, and 26 (17.4%) had verbalizations. No statistically significant differences were observed between TS patients with simple versus complex phonic tics with respect to sex, age at onset, age at presentation, or comorbid attention-deficit/hyperactivity disorder or obsessive-compulsive disorder. Patients with complex phonic tics more frequently had trunk tics (

conclusionsComplex phonic tics seem to be part of a more widely distributed, severe, and complex presentation of TS, likely representing a continuum within the spectrum of motor and phonic tics.
