The BMD approach offers several advantages over traditional methods such as NOAEL. It provides a more precise estimate of the dose-response relationship by utilizing all the data points from an experiment rather than just one. This method reduces the uncertainty associated with estimating risk, as it does not rely on the highest dose that does not produce an effect (NOAEL), which can vary significantly between studies. The BMD method also allows for the calculation of confidence limits, providing a range of doses within which the true benchmark dose is likely to lie.
