TPX Podcast 2026 Series - EP2: Absolute Versus Relative Approaches to Severity Scoring of Histopathologic Findings in Pre-Clinical Toxicology Studies: What's the Difference, and How, When, and Why This Matters

Um, first, I'd like to reemphasize that the absolute and relative scoring methods are both legitimate approaches for severity scoring, and I believe that the selection of one approach versus another is unlikely to affect the study outcome in most cases.

I think that's important to, to, to, to say.

Second, the choice of which approach is u- is used often depends upon whether a zero change baseline exists for a comparison, as we've already discussed.

And third, for types of diagnoses in which the use of either approach is feasible, the absolute approach, I think, has advantages that perhaps should be considered because absolute scoring tends to be more straightforward, more objective, and more transparent.

It creates more consistent historical control data, and the results generally align better with those of other studies and with quantitative analyses.

Yeah.

That makes sense.

Um, it does definitely make for an easier peer review and, uh, more robust historical control data.

That all makes sense to me.
