What characterizes a multi-center trial?

A multi-center trial is characterized by the involvement of more than one investigator, which allows for a broader patient population and the potential for more diverse data collection. This approach helps to enhance the generalizability of the trial results, making them more applicable to a larger segment of the population.

In multi-center trials, multiple locations may be chosen to conduct the study to ensure a sufficient sample size and to allow for variability in patient demographics, environments, and treatment responses. The involvement of different investigators also adds expertise and experience from various points, which can strengthen the integrity of the trial.

Overall, the primary hallmark of a multi-center trial is this collaborative aspect among various facilities and investigators, aimed at improving the robustness of clinical research outcomes.
