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

Figure 1 Odds ratios for clinical outcomes associated with prehospital aspirin use. Forest plot displaying the odds ratios and 95% confidence intervals for key adverse outcomes among patients with pulmonary embolism who were or were not on prehospital aspirin therapy. Prehospital aspirin use was associated with significantly lower odds of radiographic right ventricular strain, intensive care unit admission, shock, and need for catheter-directed thrombolysis (Ekosonic endovascular system). Mortality showed a strong association favoring aspirin use. A vertical dashed line indicates the null value (odds ratio = 1.0). EKOS: Ekosonic endovascular system; ICU: Intensive care unit; CT: Computed tomography; RV: Right ventricle; OR: Odds ratio.
