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.

Method [2] Wilcoxon (Mann-Whitney)
P Value [3] < 0.001
[1] Additional details about the analysis, such as null hypothesis and power calculation:
  A sample size of 212 per arm provided 90% power and > 99% power with a 2-sided alpha = 0.05 level to detect differences between treatment arms of 6% and 17% in the percent change in HDL-C and TG, respectively, assuming an SD of 19% and 30%, respectively. This sample size provided an overall power of approximately 90% for the 2 primary comparisons. If a loss to follow-up rate of 8% was assumed, the sample size needed to be increased to 230 per arm to maintain the above power.

  No text entered.
[3] Additional information, such as whether or not the p-value is adjusted for multiple comparisons and the a priori threshold for statistical significance:
  The treatment group comparisons for both primary efficacy variables must have demonstrated superiority of ABT-335 + atorvastatin + ezetimibe to declare this arm successful. Thus, no adjustments were made for multiple comparisons.
