• 3 (Simple Site)—Each site has a different drug kit list. Each new subject is assigned the next sequential drug kit number on the list for the subject's site.
• 4 (Stratified by Site)—Each site has multiple lists of drug kits. Each new subject is first assigned to the set of list for the subject's site. Then, the subject is assigned to one of the site's drug kit lists based on entered subject data. Finally, the subject is assigned the next sequential drug kit number on that list.
