[1] The same participant may be included in more than one category therefore the number of participants for this baseline measure does not equal the total number of participants in the group. Not all participants have one of these comorbidity measures.

[3] Left ventricular ejection fraction (LVEF) is an assessment of the amount of blood emptied from the left ventricle during systolic contraction, which is indicative of global ventricular function.
[4] Extent of stenosis of the target lesion (measured as percent of area stenosed)
[5] The same participant may be included in more than one category therefore the number of participants for this baseline measure does not equal the total number of participants in the group. Not all participants have one of these lesion characteristics.
[6]

Type A:minimally complex, readily accessible, non angulated, smooth contour, little to no calcification, less than totally occlusive, not ostial in location, no major side branch involvement, absence of thrombus.

Type B:moderately complex, eccentric, moderate tortuosity and angulation, moderate or heavy calcification, total occlusion < 3 months old, ostial in location, presence of thrombus; type B1 has one adverse characteristic and B2 has ≥2. Type C:severely complex, diffuse, excessive tortuosity and angulation, total occlusions > 3 months old, degenerated vein grafts and friable lesions.

[7] TIMI 0 - No perfusion; TIMI 1 - Penetration with minimal perfusion; TIMI 2 - Partial perfusion; TIMI 3 - Complete perfusion

Principal Investigators are NOT employed by the organization sponsoring the study.
There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.
The agreement is:
unchecked The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is less than or equal to 60 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
unchecked The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is more than 60 days but less than or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo.


Limitations and Caveats
Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
