A retrospective study looks back at data that has already been collected and analyzes it for potential relationships or patterns. In the case of identifying lifestyle factors related to the development of liver cancer, researchers could gather data from medical records and self-reported lifestyle choices of people who have been diagnosed with liver cancer and compare it to a control group without liver cancer. This type of study design would be the best approach as it would allow researchers to identify possible lifestyle factors that may have contributed to the development of liver cancer in the adult population. Double-blind and single-blind studies are typically used in clinical trials where the participants are randomly assigned to different treatment groups, and neither the participants nor the researchers know which group they have been assigned. In an experimental study, researchers manipulate one or more variables to see their effect on the outcome, which may not be practical or ethical for studying lifestyle factors that could increase the risk of liver cancer.
