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.
One placebo group patient dropped out due to an adverse event is not included in baseline measures or in outcome measures. Assuming 35% variability in circulating ICAM-1 concentrations,46 a sample size of 18 per group is adequate to detect a 50 percentage point difference in the percent in ICAM-1 with 80% power and an = 0.05.
