Forest plot and meta-analysis of hazard ratios (HRs) for death among patients with pancreatic cancer by (A) long- and (B) short-term diabetes status at diagnosis from Nurses' Health Study, Health Professionals Follow-up Study, and Dana-Farber Cancer Institute. Solid squares and horizontal lines correspond to study-specific multivariable-adjusted HRs and 95% CIs; area of solid square reflects cohort-specific weight (inverse of variance). Diamonds represent meta-analysis multivariable-adjusted HRs and 95% CIs. Vertical line indicates odds ratio of 1.0. HRs adjusted for age at diagnosis (continuous), sex (male or female), race/ethnicity (white, black, other, or unknown), smoking status (never, past, current, or missing), year of diagnosis (continuous), and stage at diagnosis (localized, locally advanced, metastatic, or unknown).
