A retrospective study is a study that looks back in time and analyzes previous events. In the case of AIDS, a retrospective study would analyze the medical histories of patients who had been diagnosed with the disease. This type of study was important in identifying risk factors that led to AIDS because researchers could analyze the medical histories of patients who had the disease and compare them to those who did not. Through this analysis, they were able to identify risk factors such as sexual activity, drug use, and blood transfusions that were associated with a higher risk of contracting the disease.
