This study is a case-control study, which compares the diets of individuals with pancreatic cancer (cases) to the diets of healthy individuals (controls). It aims to identify potential risk factors for pancreatic cancer, such as the consumption of barbecued meat. The matching of cases and controls based on age, sex, and body mass index helps to control for these factors and isolate the effect of diet on the development of pancreatic cancer.
