Experiences with the execution of intercultural, intercontinental trials - part I.

ABSTRACT

Large scale, international clinical trials are formidable challenges, but they are the most effective means of answering important clinical questions in a definitive, generalizable manner. They require adequate funding and must be rigorously conducted. Much can be gleaned from such studies, which address the important research questions and provide answers to related questions. Such trials are enormously rewarding and are worth the expense and effort.
