Distribution of predicted cancer risk estimates (A-B: mortality rates for bladder and kidney cancers; C: standardized mortality ratio for bladder cancer; D: incident relative risk for bladder cancer) at three levels of arsenic concentrations (10, 50 and 150 μg/L) in drinking water. Distributions were obtained from a bootstrap randomization of the fixed effects arsenic-risk models which were parameterized as a function of logged arsenic and the study from which the data were derived. A total of 10,000 randomizations were used.
