Population Description

Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
All randomized subjects with a baseline apoB value and at least 1 postbaseline apoB value, last observation carried forward.

[1]	Additional details about the analysis, such as null hypothesis and power calculation:
	Secondary endpoints were tested in fixed sequence. If superiority of ABT-335 + atorvastatin + ezetimibe treatment was demonstrated for primary endpoints, secondary endpoints were tested in ranked order of apoA1, VLDL-C, apoC3, non-HDL-C, apoB, and hsCRP at alpha = 0.05 level until 1 secondary endpoint failed to reach statistical significance.
[2]	Other relevant information, such as adjustments or degrees of freedom:
	Corresponding baseline lipid value as the covariate and with effect for treatment group.
[3]	Additional information, such as whether or not the p-value is adjusted for multiple comparisons and the a priori threshold for statistical significance:

Certain Agreements:

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:

	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.
	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.
	Other disclosure agreement that restricts the right of the PI to discuss or publish trial results after the trial is completed. Restriction Description: Not to publish or present the results before the publication of the multi-center investigator paper, but in no event shall be so restricted after the expiration of twelve (12) months from completion of the studies at all sites. Any presentation or publication to be submitted to Sponsor (in Draft of the same) for Sponsor review and comment.
