The data from the field activity at the Northridge, CA. site was received at the CRO facility of Medicus Research, LLC in Midlothian, VA using password protected electronic transfer. The Data Management staff logged in the data files as they were received; code books were developed to facilitate smooth and accurate editing and data entry. Statistician and Data Analyst trained the data entry personnel using the codebook as the guideline for instruction on operational processes for this data. Data was analyzed using paired sample t-tests for within subject means comparisons, independent sample t-tests for between group comparisons (Placebo vs. each of the active groups individually), t-tests of difference scores for both within and between group comparisons (Placebo vs. each of the active groups individually).
