Treatment Runs

This section contains the following elements.

•	Data Filter : Enables you to filter data based on study site and country.

•	Distributions : Displays histograms showing distribution of subjects across study sites, treatment arms, and run counts. Run IDs are determined, based on randomization date and usubjid , and counts are determined by the number of instances where a treatment is dispensed in a row within a site.

This is useful to determine whether randomization errors or fraud has occurred. For example, if randomization is done with a block size of 4 and equal allocation (as selected above), the most you would ever expect to see treatment A or B occur is 4 times in a row. If a treatment is dispensed 5 times in a row, this occurrence would likely require some explanation by the investigators.
