Abbreviations: CT, chest tube; HCT, hematocrit; Hgb, hemoglobin; PRU, P2Y₁₂ Reaction Units; SD, standard deviation.

All values are given as mean (SD).

Indicates statistical significance at P < 0.01.

Indicates statistical significance at P < 0.05. Significance determined by Student t test within each PRU cutpoint group.
