Frontal QRS-T Angle and the Risk of Atrial Fibrillation in the Elderly.
Article in Annals of noninvasive electrocardiology : the official journal of the International Society for Holter and Noninvasive Electrocardiology, Inc, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers, 1 of them a synthesis that pooled 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.
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
backgroundFrontal QRS-T angle reflects changes in regional action potential duration and the direction of repolarization. Although it has been suggested that abnormal ventricular repolarization predisposes to atrial arrhythmias, it is unknown whether abnormal frontal QRS-T angle is associated with an increased risk of atrial fibrillation (AF).
methodsWe examined the association between frontal QRS-T angle and AF in 4282 participants (95% white; 41% male) from the Cardiovascular Health Study (CHS). QRS-T angle was computed from baseline electrocardiogram data. Abnormal QRS-T angle was defined as values greater than the sex-specific 95th percentile (men >131°; women: >104°). AF cases were identified from study electrocardiograms and from hospitalization discharge data through December 31, 2010. Cox regression was used to compute hazard ratios (HR) and 95% confidence intervals (CI) for the association between abnormal QRS-T angle and AF.
resultsOver a median follow-up of 12.1 years, a total of 1276 (30%) participants developed AF. In a Cox regression model, adjusted for socio-demographics and known AF risk factors, abnormal QRS-T angle was associated with a 55% increased risk of AF (HR = 1.55, 95%CI = 1.23, 1.97). When QRS-T angle was examined as a continuous variable, each 10° increase was associated with a 3% increased risk of AF (HR = 1.03, 95%CI = 1.01, 1.05). This finding was consistent in subgroups stratified by age, sex, and race.
conclusionOur findings suggest that an abnormal frontal QRS-T angle on the electrocardiogram provides important prognostic information regarding AF risk in the elderly, and further implicate ventricular repolarization abnormalities in the pathogenesis of AF.
