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
objectiveTic disorders (TD) often present with associated neuropsychiatric comorbidities. This study aims to examine the clinical manifestations of TD in pediatric patients and explore the spectrum and features of neuropsychiatric comorbidities among Chinese children diagnosed with TD.
methodsA retrospective analysis was conducted on pediatric TD cases newly diagnosed at our institution, using the Mini International Neuropsychiatric Interview for Children and Adolescents 5.0 to screen for comorbidities. Furthermore, a statistical analysis of clinical features was undertaken.
resultsThe study enrolled 182 patients, comprising 140 males and 42 females. The diagnoses were distributed as follows: 65 cases of provisional TD, 29 cases of chronic TD, and 88 cases of Tourette syndrome. 94 (51.65%) patients presented with at least a single neuropsychiatric comorbid, while 40 (21.98%) patients exhibited two or more such comorbidities. TD is most frequently comorbid with attention-deficit hyperactivity disorder (33.52%, 61/182), oppositional defiant disorder (11.00%, 20/182) and current/previous manic/hypomanic episode (7.69%, 14/182). Children with comorbidities, compared to those without, experienced delayed diagnosis (P = 0.039), were more prone to developing vocal tics (simple vocal tics P = 0.030, complex vocal tics P < 0.001), lacked sibling companionship (P = 0.030), and exhibited more severe tics (P = 0.008). The prevalence of comorbidities was notably higher in children from single-parent households (93.3%) compared to those in two-parent families (P = 0.006). Individuals with multiple comorbidities had delayed diagnosis (P = 0.013), and notably experienced more triggering psychological factors such as pressure, anxiety, and anger. Sex, parents' educational backgrounds and severity of tics significantly related to specific comorbidity occurrence.
conclusionWe identified several factors associated with comorbidities in children with TD, which aiding doctors in recognizing the comorbidities that require attention. Simultaneously, these factors help guide family members in providing targeted education that supports the physical and mental development of affected children.
