PT: prothrombin time, INR: international normalized ratio, APTT: activated partial thromboplastin time.

SONACT: sonoclot activated clotting time, CR: clot rate, PF: platelet function, TP: time to peak, PA: peak amplitude.

r: Spearmans rank correlation coefficient.

P value is significant if <0.05.
