Abbreviations: BMI, body mass index; CFT, clot formation time; CT, clotting time; eGFR, estimated glomerular filtration rate; HGB, hemoglobin; MCF, maximum clot firmness; ML, maximum lysis; PAI‐1, platelet activator inhibitor‐1.

Notes: Significance level: **P ≤ .01; *P ≤ .05; +P ≤ .10. CT and ML were not included for EXTEM, as regression model was not statistically significant.
