Study-specific and pooled odd ratios^a (ORs) for pancreatic cancer by history of diabetes 2 or more years before cancer diagnosis (or interview for controls) when compared with no history. Data from Pancreatic Cancer Case-Control Consortium (PanC4). 95% CI, 95% confidence interval; LSU, Louisiana State University; MDACC, MD Anderson Cancer Center; MSKCC, Memorial Sloan Kettering Cancer Center; NCI, National Cancer Institute; SEARCH, Surveillance of Environmental Aspects Related to Cancer in Humans; UCSF, University of California, San Francisco; UMN, University of Minnesota. ^aStudy-specific ORs were computed from logistic regression models adjusted for center (for multicenter studies), age, sex, race/ethnicity, education, body mass index, tobacco smoking, alcohol drinking (except for the MSKCC study), and history of pancreatitis (except for the Italy, Mayo Clinic, and Penn State studies). Pooled ORs were further adjusted for study. Homogeneity of ORs between studies was based on likelihood ratio tests and the resulting χ² statistic.
