Details on study design:

The profiler contains category boundaries to be expected to induce similar toxicological effects in repeated dose oral toxicity. These category boundaries were developed based on repeated dose toxicity test data in the database of Hazard Evaluation Support System (HESS). Justification for each category (mechanistic or empirical information) is described.
