Because it is relatively simple, results are quick, and manpower and material resources are saved, more and more epidemiologists are receiving The welcome-case-control study can be seen as an extension of the doctor’s asking and writing of medical records, and it is a more scientific method than “clinical case analysis” because it adds a “disease-free” in addition to the analysis of cases.
