Influence of seasons on the management and outcomes acute myocardial infarction: An 18-year US study.
Article in Clinical cardiology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
backgroundThere are limited data on the seasonal variation in acute myocardial infarction (AMI) in the contemporary literature. HYPOTHESIS: There would be decrease in the seasonal variation in the management and outcomes of AMI.
methodsAdult (>18 years) AMI admissions were identified using the National Inpatient Sample (2000-2017). Seasons were classified as spring, summer, fall, and winter. Outcomes of interest included prevalence, in-hospital mortality, use of coronary angiography, and percutaneous coronary intervention (PCI). Subgroup analyses for type of AMI and patient characteristics were performed.
resultsOf the 10 880 856 AMI admissions, 24.3%, 22.9%, 22.2%, and 24.2% were admitted in spring, summer, fall, and winter, respectively. The four cohorts had comparable age, sex, race, and comorbidities distribution. Rates of coronary angiography and PCI were slightly but significantly lower in winter (62.6% and 40.7%) in comparison to the other seasons (64-65% and 42-43%, respectively) (P < .001). Compared to spring, winter admissions had higher in-hospital mortality (adjusted odds ratio [aOR]: 1.07; 95% confidence interval [CI]: 1.06-1.08), whereas summer (aOR 0.97; 95% CI 0.96-0.98) and fall (aOR 0.98; 95% CI 0.97-0.99) had slightly lower in-hospital mortality (P < .001). ST-segment elevation (10.0% vs 9.1%; aOR 1.07; 95% CI 1.06-1.08) and non-ST-segment elevation (4.7% vs 4.2%; aOR 1.07; 95% CI 1.06-1.09) AMI admissions in winter had higher in-hospital mortality compared to spring (P < .001). The primary results were consistent when stratified by age, sex, race, geographic region, and admission year.
conclusionsCompared to other seasons, winter admission was associated with higher in-hospital mortality in AMI in the United States.
