Alcohol: 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.

?Collecting evidenceAn apparent alcohol-improves-deep-sleep result did not meet the device-coverage standard and was not published as a finding.
Not explained by the science yetThe alcohol-improves-deep-sleep claim was not published as a finding. Established polysomnography research says alcohol disrupts deep and REM sleep architecture, which is consistent with the reviewed result.
