Estimated effects from the age-period-cohort model (non-Hodgkin's lymphoma, age group 20-89 years, 1980-2005, Doubs region, France). The centermost curve represents the age-specific rates for 100,000 person-years at risk during the reference period (1980). The median curve shows the rate ratios of cohorts conditional on the estimated age and period effects. The rightmost curve shows the rate ratios of periods relative to the reference period (1980). Fitted values are plotted together with 95% confidence limits.
