The choice of study design is critical in toxicology as it dictates the framework for data collection and analysis. Common designs include in vitro, in vivo, and epidemiological studies. Each design has its strengths and limitations, and the choice largely depends on the research question. For instance, in vitro studies allow for controlled experimentation but may not fully replicate complex biological systems, whereas in vivo studies provide more comprehensive data but involve ethical considerations and higher costs.
