American Journal of Drug and Alcohol Abuse
Special CTN Issue: v. 37(5), 2011

This special issue brings together articles that reflect 12 years of experience in the National Drug Abuse Treatment Clinical Trials Network (CTN), with methodological and statistical issues that arise in the design and conduct of controlled, multi-site, community-based effectiveness trials. To date, the CTN has randomized over 13,000 patients into 27 completed trials, with more trials currently ongoing, providing a wealth of experience in design, implementation, and analysis of effectiveness trials.
