Primary	Change From Baseline in Reactive Hyperemia Index (RHI) on Day 13	RHI is a measure of the extent of vessel dilatation and augmentation in vascular blood flow after a prespecified period of flow interruption. RHI is determined as the ratio of the post-to-pre- occlusion peripheral arterial tonometry amplitude of the tested (occluded) arm, divided by the post to-pre-occlusion ratio of the control arm. RHI values >1.67 indicate normal endothelial function, while values =1.67 indicate endothelial dysfunction.	Baseline, Day 13 predose AM
Primary	Post-Baseline Platelet Reactivity on Days 8 and 14: P2Y12 Reaction Units (PRU) Assay	Platelet reactivity, as measured by VerifyNow PRU assay, and presented as number of participants with < 180 PRU or = 180 PRU post-baseline (Days 8 and 14), by baseline category.; The VerifyNow PRU assay measures effects on platelet activation caused by inhibition of the platelet receptor, P2Y12. This receptor is activated by adenosine 5'-diphosphate (ADP) in the cascade leading to platelet aggregation but can be blocked by P2Y12 inhibitor drugs, such as clopidogrel. Blockage of this receptor diminishes platelet activation and the ability of platelets to bind to fibrinogen. VerifyNow PRU assay values < 180 units indicate impairment of platelet aggregation.	Baseline, Day 8, Day 14
Primary	Post-Baseline Platelet Reactivity on Days 8 and 14: Aspirin Reaction Units (ARU) Assay	Platelet reactivity, as measured by VerifyNow ARU assay, and presented as number of participants with = 549 ARU or > 549 ARU post-baseline (Days 8 and 14), by baseline category.; Aspirin irreversibly inhibits cyclooxygenase 1, which converts arachidonic acid to thromboxane A2, which in turn is involved in the activation of the glycoprotein (GP)IIb/IIIa receptor necessary to initiate platelet aggregation. Impairment of platelet aggregation of the aspirin type is defined for the VerifyNow aspirin assay as values = 549 ARU.	Baseline, Day 8, Day 14
Primary	Change From Study Baseline Over Time in Platelet Function Assessments: PRU Assay	The VerifyNow PRU assay measures effects on platelet activation caused by inhibition of the platelet receptor, P2Y12. This receptor is activated by adenosine 5'-diphosphate (ADP) in the cascade leading to platelet aggregation but can be blocked by P2Y12 inhibitor drugs, such as clopidogrel. Blockage of this receptor diminishes platelet activation and the ability of platelets to bind to fibrinogen. VerifyNow PRU assay values <180 PRU indicate impairment of platelet aggregation.	Study Baseline (Day 1 predose), Day 8 (predose AM), Day 14 (predose AM)
Primary	Change From Study Baseline Over Time in Platelet Function Assessments: ARU Assay	Aspirin irreversibly inhibits cyclooxygenase 1, which converts arachidonic acid to thromboxane A2, which in turn is involved in the activation of the GPIIb IIIa receptor necessary to initiate platelet aggregation. Impairment of platelet aggregation of the aspirin type is defined for the VerifyNow aspirin assay as values = 549 ARU.	Study Baseline (Day 1 predose), Day 8 (pre AM dose), Day 14 (pre AM dose)
Primary	Percent Change From Study Baseline Over Time in HOMA-IR in Participants Without Concomitant Use of Insulin	Blood samples were taken for fasting glucose and insulin levels. From these results, insulin resistance was then estimated using the updated homeostasis model assessment method for insulin resistance (HOMA-IR) computer algorithm. A higher HOMA-IR indicates a higher degree of insulin resistance. Typically a cutoff of HOMA-IR for identifying those with insulin resistance is 2.5.
