Increase of colon cancer incidence by drinking water nitrate in Iowa. Increase of incidence of colon cancer (and 95% confidence intervals) in Iowa public water supply, for subgroups with above and below median dietary and medical risk factors, and with 1-10 years of exposure and more than 10 years of exposure to NO3-concentrations in drinking water exceeding 25 mg/L NO3, relative to the subgroup with no exposure (after [14]).
