We take what shifts this modifier is known to make and the shifts reported for a symptom. There are many bacteria involved. We sum all of the shifts (some positive and some negative) to estimate a predictor. Some bacteria may have greater impact (that information is not available in 99% of studies) so the estimate can be wrong in edge cases.
This is based on associations discovered from annotated 16s microbiome samples. See this post for more information.

We extend modifiers to include items that changes the parent and child taxa. I.e. for a species, that would be the genus that is belongs to and the strains in the species.
