title: [Quantitative risk assessment: extrapolation methods from high doses to low doses].
abstract: Two methods of linear extrapolation from high to low doses were discussed. The first method depended on fitting a particular model (multistage, logistic) from the experimental data and then on extrapolating from the point on the dose-response curve to the lowest positive dose level employed. The linearized multistage model of carcinogenesis was used in the second method--the results obtained were highly conservative.
