Figure 1: Box-plots for the data distribution in relation to need for blood transfusion. Multiplate analyser for ASPI (immediately pre-op and post protamine) showing significantly (p<0.01) low values for Group A (anti-platelet till day of surgery) TEG data (R and MA) post protamine demonstrating no significant differences (p=0.4) between the values for Groups A & B and hence non-predictive for the need for blood transfusion
