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

objectiveThis longitudinal study examined the impact of tic disorders on autonomic nervous system function using heart rate variability (HRV) as a biomarker and assessed its association with quality of life over a 1-year period.

methodsThe patient group comprised 39 individuals, of whom 19 were followed up after 1 year, whereas the control group included 30 individuals. Tic severity and quality of life were assessed using the Yale Global Tic Severity Scale and KIDSCREEN-27 questionnaire, respectively. HRV parameters were used to measure autonomic function during this period.

resultsAt baseline, patients with tic disorders demonstrated lower HRV, particularly in low-frequency (LF) power, and a higher standard deviation of the average normal-to-normal intervals, indicating significant autonomic dysregulation compared to control participants. Over the 1-year follow-up period, these patients demonstrated a decline in HRV indices, particularly LF power. HRV metrics and quality of life scores exhibited significant correlations at baseline, indicating that a better autonomic balance status was associated with perceived better quality of life. During follow-up, the correlations between HRV measures and psychological/behavioral scales observed at baseline were altered and no longer significant, potentially reflecting the effects of treatment and homeostatic adaptation over time.

conclusionTic disorders are associated with persistent autonomic dysfunction, which progressively impair physiological regulation and quality of life. The findings of this study elucidate the significance of incorporating strategies for autonomic modulation into treatment plans for patients with tic disorders.
