As you may have noticed, the ITN website has undergone some pretty majorchanges. We hope you enjoy the new look and will find the new site easier tonavigate and as informative as our previous versions. Our website has gone through several iterations since the ITN was founded in 1999. Prior to this redesign, the last revision took place in May 2002, whenthe ITN was still relatively young and was conducting only a handful of clinical trials.
