Not all details of the DEB theory are used in this method; effects on survival as specified by the hazard model hardly uses any detail of the DEB theory, for instance, but is fully consistent with how DEB theory deals with aging as a result of the effects of free radicals.
Not every aspect of the DEB hypothesis is employed in this method; the effects on longevity as described by the hazard model mostly ignores the intricate details of the DEB hypothesis, but it is fully in line with how the DEB hypothesis handles aging resulting from the effects of free radicals.
