Timing of stroke risk reassessment in atrial fibrillation patients with a CHA2DS2-VA score of 0 or 1: the Norwegian AFNOR study.

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
aimsStroke risk in atrial fibrillation (AF) patients increases over time, but the optimal reassessment interval remains unclear. This study evaluated changes in the CHA2DS2-VA score in AF patients with low (score 0) or intermediate (score 1) stroke risk and explored appropriate reassessment intervals. METHODS AND
resultsUsing Norwegian national registries (2011-18), 40 782 individuals with incident AF aged ≥18 years and a low or intermediate CHA2DS2-VA score were identified. Patients were followed from first AF diagnosis until an increase in the CHA2DS2-VA score, and the proportion with increased score was assessed across age groups. The number needed to reassess to detect one new CHA2DS2-VA risk factor was calculated at different time intervals after AF diagnosis. The CHA2DS2-VA score increased in 50% of patients after a median follow-up of 1.7 years. The proportion of patients with an increased CHA2DS2-VA score was 19% at 6 months, 25% at 1 year, and 40% at 3 years after AF diagnosis. At 1 year, the proportion of patients with a new risk factor was lower in those aged 18-44 years (8%) and 45-54 years (14%) compared to those aged >55 years (30%), with the number needed to reassess at 1 year being 12, 7, and 3 patients, respectively.
conclusionNew risk factors emerged in half of AF patients within 1.7 years. Age-specific differences underscore the need for tailored reassessment, suggesting a shorter interval of 6 months for patients ≥55 years and 1 year for those <55 years and routinely at age 65 and 75 years.
