Prevalence of Restless Legs Syndrome in Patients Who Underwent Percutaneous Coronary Intervention in a Tertiary Care Hospital: A Cross-Sectional Study.
Article in Annals of Indian Academy of Neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND AND
objectivesRestless legs syndrome (RLS) is a risk for cardiovascular diseases and increases the risk of adverse cardiovascular outcomes following percutaneous coronary intervention (PCI). We aimed to determine the prevalence of RLS and its associated factors among coronary artery disease (CAD) patients undergoing PCI.
methodsThis was a cross-sectional study conducted among CAD patients undergoing PCI at a tertiary care institute in India. All study participants underwent a detailed evaluation of RLS symptoms. Clinical and sleep evaluations were done through a prestructured questionnaire, Pittsburgh Sleep Quality Index, Berlin Questionnaire, and Epworth Sleepiness Scale. RLS was diagnosed according to the International Classification of Sleep Disorders-3 rd edition. The symptoms and severity were characterized by using the All India Institute of Medical Sciences (AIIMS) RLS Questionnaire for Indian Patients and the International Restless Legs Syndrome Study Group (IRLSSG) rating scale.
resultsOf 116 post-PCI study participants, with a mean age of 51.9 ± 8.5 years and in whom males constituted 92.5%, 25 (21.6%, 95% confidence interval = 14-30) patients had RLS. The prevalence of RLS was significantly higher among those with poor sleep quality (27.5% vs. 8.33%, P = 0.02). Among patients with RLS, the mean (standard deviation [SD]) age of onset of symptoms was 48.5 (10.2) years, and its median (interquartile range) duration was 24 (8-42) months. Mean (SD) IRLSSG score was 17.2 ± 7.3. Four (16%) patients had mild RLS, 14 (56%) had moderate RLS, six (24%) had severe RLS, and one (4%) had very severe RLS.
conclusionsOne in five patients with PCI had RLS. Identification and optimal treatment of RLS in these patients could improve their quality of life.
