Watching the Game, Skipping the Hospital: World Cup Matches and Cardiovascular Hospitalizations.
Article in Cardiology research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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
Background: Major sporting events may acutely alter patterns of cardiovascular hospitalization through changes in healthcare-seeking behavior, hospital utilization, and emotional or behavioral triggers. Brazil participated in the FIFA World Cup in 2014 (as host), 2018, and 2022, providing a unique natural experiment. Methods: We analyzed daily counts of acute myocardial infarction (AMI, ICD-10 I21) and heart failure (HF, ICD-10 I50) hospitalizations from the Brazilian national hospital information system (SIH-SUS) during three ± 30-day windows around each World Cup tournament (2014, 2018, 2022). Negative binomial regression models estimated incidence rate ratios (IRRs) for Brazil match days versus non-match days, controlling for day of week, month, and year fixed effects. Results: On Brazil match days, AMI admissions were 7.0% lower than non-match days (IRR 0.930, 95% confidence interval (CI) 0.898-0.962, P < 0.001) and HF admissions were 11.1% lower (IRR 0.889, 95% CI 0.855-0.925, P < 0.001). Conclusions: Brazil World Cup matches were associated with significant reductions in same-day AMI and HF hospitalizations. These findings highlight the potential impact of major sporting events on hospital utilization and cardiovascular care access.
