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

Background: Restless legs syndrome (RLS) is highly prevalent among end-stage renal disease (ESRD) patients undergoing dialysis, causing significant sleep disruption. Whether dialysis modality influences RLS occurrence remains controversial. This study compared RLS prevalence, severity, and sleep outcomes between hemodialysis (HD) and peritoneal dialysis (PD) patients using propensity score matching. Methods: From April to October 2024, 396 ESRD patients (173 HD, 223 PD) were enrolled. RLS was diagnosed using IRLSSG 2014 criteria. Sleep quality was assessed using Pittsburgh Sleep Quality Index (PSQI ≥11 indicating clinically significant sleep disturbance). 1:1 propensity score matching was performed on age, sex, education, dialysis vintage, smoking, alcohol consumption, and comorbidities. Matched groups (140 HD, 140 PD) were compared for RLS prevalence, severity, and sleep outcomes. Results: After matching, RLS prevalence was comparable between HD and PD (39.28% vs. 40.00%, Conclusion: HD and PD showed similar RLS prevalence but divergent sleep disturbance patterns. Distinct risk factor profiles suggest dialysis-specific mechanisms differentially influence RLS pathophysiology. β2-Microglobulin emerged as a universal risk factor, supporting unified, risk factor-based screening strategies to improve sleep quality in dialysis populations regardless of modality.
