High Neutrophil-to-Platelet Ratio Is Associated with Poor Survival in Patients with Acute Aortic Dissection

Figure 1

Kaplan–Meier survival curve analysis. (a) Patients with acute aortic dissection were stratified according to the NPR value, and the difference in the overall survival time was calculated using the Kaplan–Meier analysis. The Kaplan–Meier curve shows the difference in the overall survival time between (b) type A aortic dissection (TAAD) and type B aortic dissection (TBAD) and (c) treatment methods. The p.adj is obtained by multiple hypothesis test using Bonferroni method to correct the significance level. TEAR: thoracic endovascular aortic repair; CM: conservative management; ST: surgical treatment.
