We selected additional controls for bladder cancer cases diagnosed from July 1, 1995 to June 30, 1997 frequency matched to these cases on age (25–34, 35–44, 45–54, 55–64, 65–69, 70–74 years) and gender. Controls were randomly assigned a reference date from among the diagnosis dates of the case group to whom they were matched. We interviewed a total n = 665 controls (the total shared control group and additional controls), which was 70% of the controls confirmed to be eligible for the study. Of the potential participants, ( n = 18) were reported as deceased by a member of the household, ( n = 17) no answer after 40 attempts distributed over day, evenings and weekends, ( n = 261) declined, ( n = 29) were mentally incompetent or too ill to take part.
