Those mathematical products which have been developed normally investigate an individual disturbance only.

Disorder related morbidity, mortality, and progression might be quite variable and may drastically impression the necessity for drug dosing individualization. If precision dosing were being to result in significant mortality reductions for the sickness/drug combination, that alone would probably outweigh any factors that indicated that a drug would otherwise not be a superb prospect for specific dosing.
