Abbreviations: ADP, adenosine diphosphate; ASPI, aspirin; BMI, body mass index; eGFR, estimated glomerular filtration rate; ETP, endogenous thrombin potential; HGB, hemoglobin; TRAP, thrombin receptor activating peptide.

Notes: Significance level: ** P ≤ .01; * P ≤ .05; + P ≤ .10. Time to peak was not included as regression model was not statistically significant.
