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
introductionhigh blood pressure (HBP), atrial fibrillation (AF) and ischemic stroke are three public health problems. The purpose of this study was to determine the prevalence of AF and ischemic stroke in hypertensive patients and the factors associated with the occurrence of non-valvular AF in these patients.
methodswe used data collected in the Department of Cardiology at the University Hospital of Sfax as a part of National Tunisian Registry of Hypertension. We examined the associations between different socio-demographic, clinical, paraclinical, and therapeutic variables and AF in hypertensive patients using logistic regression models.
resultsour sample consisted of 2887 patients with a sex ratio of 0.95. The average age of patients was 65 years (±11). AF was found in 230 patients (8%), while ischemic stroke was found in 152 patients (5.3%). Multivariate analysis highlighted that independent factors associated with an increase in the prevalence of AF were: advanced age (p = 0,001, Odds Ratio (OR) = 1,647, 95% confidence interval ( CI): 1,1227-2,213), the detection of left ventricular hypertrophy (LVH) on cardiac ultrasound (p= 0,004, OR= 2,140, 5%CI 9: 1,281-3,576), and left ventricular ejection fraction (LVEF) < 50% (p<0,001, OR=4,677, 95% CI: 2,715 and 8.057).
conclusionthis study confirms that there is a direct and independent relationship between high blood pressure, advanced age, LVH and AF. AF in patients with high blood pressure is a disease progression leading to an increased risk of ischemic stroke. Optimal high blood pressure control is a priority in hypertensive patients, especially in the elderly, aiming at preventing the risk of AF and ischemic stroke.
