Prehospital aspirin use is associated with improved clinical outcomes in pulmonary embolism: A retrospective case-control study

Figure 2 Distribution of pulmonary embolism severity by prehospital aspirin use Bar chart comparing the proportion of patients presenting with massive, submassive, and mild pulmonary embolism based on prehospital aspirin use. A lower percentage of massive pulmonary embolism was observed in the aspirin group, suggesting a potential attenuation of initial thrombotic severity. Percentages are based on total patients within each subgroup.
