Early Rhythm Control of Atrial Fibrillation in Cancer Survivors: A Nationwide Population-Based Study.
Observational study in Journal of the American Heart Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundAlthough early rhythm control (ERC) is effective in reducing stroke in patients with atrial fibrillation (AF), its benefits have not been well elucidated in cancer survivors. This study aimed to compare the risk of ischemic stroke between ERC and usual care in cancer survivors with AF.
methodsThis nationwide observational study was conducted using the Korean National Health Insurance Service database. Patients aged ≥20 years with newly diagnosed AF between 2009 and 2018 were included. Patients who received rhythm control therapy within 1 year of AF diagnosis were defined as the ERC group, while the remaining patients were defined as usual care group. The risk of ischemic stroke in the ERC group was compared with those of the usual care group in cancer survivors (cancer diagnosis ≥5 years) and the noncancer group.
resultsA total of 591 692 patients were included in the study (18 747 patients [3.2%] with cancer; mean age, 65.7±14.6 years; 53.7% men). During a mean 4-year follow-up, stroke occurred in 52 500 patients (1338 cancer survivors and 51 182 noncancer survivors). The ERC group showed a lower risk of stroke than the usual care group, regardless of the presence of a cancer history (adjusted hazard ratio, 0.67 [95% CI, 0.58-0.76] in cancer survivors versus 0.76 [95% CI, 0.74-0.78] in the noncancer group).
conclusionsERC is associated with a lower risk of ischemic stroke among cancer survivors. An integrated approach that incorporates appropriate rhythm control strategies should be considered for cancer survivors with newly diagnosed AF.
