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

This study aimed to assess autonomic dysfunction in patients with Familial Mediterranean Fever (FMF), and to explore its association with disease characteristics and comorbidities. Thirty FMF patients and 30 healthy controls were enrolled in this cross-sectional study. Disease features and quality of life were recorded using the Familial Mediterranean Fever Quality of Life Scale (FMF-QoL). The Composite Autonomic Symptom Score-31 (COMPASS-31), Hospital Anxiety and Depression Scale (HADS), Fatigue Severity Scale (FSS), Jenkins Sleep Scale (JSS), and Fibromyalgia Rapid Screening Tool (FiRST) were noted. Parasympathetic nervous system was evaluated by R-R interval variability (RRIV) during normal and deep breathing and 30:15 ratio tests with electromyography, while the sympathetic nervous system was assessed by sympathetic skin response (SRR), blood pressure response to standing and sustained handgrip tests. FMF patients had higher total median COMPASS-31 scores than controls (15.09 vs. 5.12, p = 0.001), with significantly higher secretomotor, gastrointestinal, bladder, and pupillomotor subdomain scores (p < 0.05). RRIV during normal breathing was lower in the FMF group compared with controls (17.29 vs. 21.27, p = 0.015). No between-group differences were observed in sympathetic function tests (p > 0.05). In correlation analyses, RRIV during normal breathing correlated negatively with CRP (r = − 0.378, p = 0.04). Sympathetic parameters showed negative correlations with CRP (left plantar SSR latency: r = − 0.398, p = 0.03; blood pressure response to handgrip: r = − 0.405, p = 0.026) and with annual attack frequency (left plantar SSR amplitude: r = − 0.449, p = 0.01). Total COMPASS-31 scores correlated with FMF-QoL (r > 0.5, p < 0.001), HADS-anxiety (r = 0.550, p = 0.002), HADS-depression (r = 0.633, p < 0.001), FSS (r = 0.600, p < 0.001), JSS (r = 0.705, p < 0.001), and FiRST (r = 0.598, p < 0.001). FMF patients showed predominant parasympathetic dysfunction, while sympathetic findings were limited to correlations suggesting possible subclinical involvement. These autonomic alterations may contribute to reduced quality of life and associated symptoms such as fatigue, depression, and sleep disturbance.
