The impact of screening-detected atrial fibrillation and associated outcomes on quality of life.
Trial report in Quality of life research : an international journal of quality of life aspects of treatment, care and rehabilitation, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02036450 (Atrial Fibrillation Detected by Continuous ECG Monitoring Using Implantable Loop Recorder to Prevent Stroke in High-risk Individuals.), which is not on this 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.

Abstract
purposeTo investigate health-related quality of life (HRQoL) after atrial fibrillation (AF) detected by screening compared with conventional AF diagnosis.
methodsWe used HRQoL data (EQ-5D-5L) from 6004 persons randomised to AF screening with implantable loop recorder and treatment (n = 1501) or to usual care (n = 4503). Annual assessments yielded individual EQ-5D-5L-index (worst=-0.76 best = 1.00) and EQ-VAS scores (Visual Analogue Scale, 0 = worst, 100 = best). Changes were estimated with linear mixed models from before to after incident AF, stroke, and major bleeding. Interaction analyses assessed differences between the randomisation groups.
resultsDuring three years of follow-up, 693 of 6004 (12%) participants were diagnosed with AF (Screening: 424 of 1501 (28%), usual care: 269 of 4503 (6.0%)), with 636 alive at year three. For participants developing AF, the EQ-5D-5L index score in the screening group declined from 0.87 before to 0.85 after AF (p < 0.001), and from 0.83 before to 0.79 after AF (p < 0.001) in usual care, with less HRQoL decline in the screening group (p = 0.019). For patients developing stroke and major bleeding, the EQ-5D-5L index scores in the screening group declined from 0.82 to 0.78 (p < 0.001) and 0.82 to 0.76 (p < 0.001) before and after diagnosis, and from 0.84 to 0.76 (p < 0.001) and 0.85 to 0.76 (p < 0.001) in usual care, without differences between the randomisation groups. All EQ-VAS analyses yielded very similar results.
conclusionAF detected through screening had little negative impact on HRQoL compared with AF detected by usual care. Stroke and major bleeding were followed by large HRQoL reductions, regardless of randomisation group.
