Burden of atrial fibrillation and atrial flutter attributable to smoking in the G20: Trends from 1990 to 2021 and predictions for 2022 to 2050: A secondary dataset analysis of the Global Burden of Disease (GBD) 2021.

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
introductionAtrial fibrillation and atrial flutter (AF/AFL) are major contributors to the cardiovascular disease burden in G20 countries. However, comprehensive assessments of smoking-attributable AF/AFL burden across the G20 remain limited. The objective of this study was to evaluate temporal trends in the AF/AFL burden attributable to smoking in G20 countries from 1990 to 2021 and to project future trends through 2050.
methodsThis secondary analysis used data from the Global Burden of Disease (GBD) 2021 study. Smoking-attributable disability-adjusted life years (DALYs), deaths, years lived with disability (YLDs), and years of life lost (YLLs) for AF/AFL were extracted for G20 countries between 1990 and 2021. Trends were analyzed by age, sex, and country, and estimated annual percentage changes (EAPCs) were calculated. Autoregressive integrated moving average (ARIMA) and exponential smoothing (ES) models were applied to project the disease burden from 2022 to 2050.
resultsIn 2021, smoking-attributable AF/AFL accounted for 321761.89 DALYs (95% UI: 187788.89-476327.05) in the G20. Overall age-standardized rates remained relatively stable from 1990 to 2021. Japan showed a declining trend, whereas Saudi Arabia and Indonesia exhibited increasing burdens. Males consistently experienced higher burdens than females, and the highest absolute burden occurred in individuals aged 65-89 years. Projections indicate that from 2022 to 2050, absolute numbers of deaths, YLDs, YLLs, and DALYs attributable to smoking-related AF/AFL will continue to rise, particularly among males, despite stable or slightly declining age-standardized rates.
conclusionsAlthough age-standardized smoking-attributable AF/AFL rates in G20 countries have remained largely stable, absolute burdens are expected to increase substantially due to population growth and ageing. Pronounced sex- and country-level heterogeneity highlights the need for sustained and targeted tobacco control and cardiovascular prevention strategies.
