Kerala Atrial Fibrillation Registry: a prospective observational study on clinical characteristics, treatment pattern and outcome of atrial fibrillation in Kerala, India, cohort profile.
Observational study in BMJ open, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 papers.
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
purposeLimited published data exist on the clinical epidemiology of atrial fibrillation (AF) in South Asia including India. Most of the published data are from the Western countries and the Far East. The Kerala AF registry was initiated to collect systematic, prospective data on clinical characteristics, risk factors, treatment pattern and outcomes of consecutive AF patients who consulted cardiologists across the state of Kerala, India.
participantsAll newly diagnosed and previously reported patients aged ≥18 years with documented evidence of AF on ECG were included. Patients with transient AF due to infection, acute myocardial infarction, alcohol intoxication, metabolic abnormalities and AF seen in postoperative cases and critically ill patients with life expectancy less than 30 days were excluded. FINDINGS TO DATE: A total of 3421 patients were recruited from 53 hospitals across Kerala from April 2016 to April 2017. There were 51% (n=1744) women. The median age of the cohort was 65 (IQR 56-74) years. Hypertension, diabetes mellitus and dyslipidaemia were present in 53.8%, 34.5% and 42.2% patients, respectively. Chronic kidney disease was observed in 46.6%, coronary artery disease in 34.8% and heart failure (HF) in 26.5% of patients. Mean CHA FUTURE PLANS: Currently, this is the largest prospective study on AF patients from India, and the cohort will be followed for 5 years to observe the treatment patterns and clinical outcomes. The investigators encourage collaborations with national and international AF researchers. TRIAL REGISTRATION NUMBER: CTRI/2017/10/010097.
