Obstacles in multinational clinical trials. In Question #16, the participants with global clinical trial experience were asked to rate 7 potential obstacles faced in a multinational clinical trial by their level of seriousness according to a 4-tier scale: a serious problem, a problem, a small problem, and no problem. The proportion of doctors responding as “a serious problem and a problem” and “a small problem and no problem” in each institution were compared. 24 and 61 doctors with global clinical trial experience at KUHP and SNUH, respectively, were answered in the question.
