Refining the risk estimates for these exposures will require additional toxicity and exposure data on multiple compounds.
This is necessary, because refining the risk assessments for chemicals that had individual concerns will not necessarily result in acceptable risks from combined exposures.
The proposed approach, applicable to metals in general, can be used in the context of REACH, for refining the risk characterisation and guiding the selection of risk management measures.
2) By refining the risk for future diabetes with the 1-h PG, the specificity and PPV of the model is significantly improved (Table 3).
Over the intervening years there has also been a steady shift towards lower rATG dosing as experience has grown, refining the risk:benefit balance.
It is also possible that new biomarkers are identified that might contribute to the decision tree, or that previously tested biomarkers might be useful for refining the risk stratification.

Considerable scientific expertise is required for PPP producers to be able to further refine the risk assessment and for the assessment authority bodies to understand the measures involved.
Advanced techniques such as biologically-based dose response models are used to refine the RVs and probabilistic models to account for uncertainties and variabilities in exposure and dose-response are used to refine the risk estimates for the chemicals that drive the value of HI for the combined exposures.
Gene testing can be undertaken which can help refine the risk estimate.
In melanoma, prognostic biomarkers are needed that would help to refine the risk of progression and assess the outcome [ 2].
If this fails to refine the risk quotient to <1 then appropriate risk management measures may need to be put in place.
