Butyrate: what it changed, and what it did not
One intervention, every measured benefit and result that did not improve. See who it moved for, where it stayed neutral or went the other way, and the next hypothesis Phoenix can validate.

How to read this
Observational research: real APOE4 carriers tracked over time, each compared with their own earlier self. Members chose their interventions, with no randomisation or placebo group. Everything else they changed is shown beside each result.

This result is under review: Not printed as of Release 001: the published +32.5% HDL case could not be re-confirmed against the member it was attributed to in the 23-Aug data pull. Held pending a correct member match, not printed as a finding.
