Weekend Effect in the Management and Outcomes of Acute Myocardial Infarction in the United States, 2000-2016.
Article in Mayo Clinic proceedings. Innovations, quality & outcomes, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 21 papers, 1 of them a synthesis that pooled it.
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
objectiveTo assess the effects of weekend admission vs weekday admission on the management and outcomes of acute myocardial infarction (AMI).
methodsAdult ST-segment elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI) hospital admissions were identified using the National (Nationwide) Inpatient Sample (2000-2016). Interhospital transfers were excluded. Timing of coronary angiography (CA) and percutaneous coronary intervention (PCI) relative to the day of admission was identified. Outcomes of interest included in-hospital mortality, receipt of early CA, timing of CA and PCI, resource utilization, and discharge disposition for weekend vs weekday admissions.
resultsOf the 9,041,819 AMI admissions, 2,406,876 (26.6%) occurred on weekends. Compared with 2000, in 2016 there was an increase in weekend STEMI (adjusted odds ratio [aOR], 1.12; 95% CI, 1.08-1.16;
conclusionDespite small differences in CA and PCI, there were no differences in in-hospital mortality of AMI admissions on weekdays vs weekends in the United States in the contemporary era.
