The swarm's case

receipt 6892: EGLN1 in microglia, braak

power
full sample +0.22 (p 0.389, n 18), 95% CI -0.28 to +0.62. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.14 (p 0.573, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: +0.14 (p 0.573, n 18). could be the mix.
skeptic
leave-one-out range +0.10 to +0.33, sign flips 0; without severely affected donors +0.22 (p 0.389, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for EGLN1 in microglia.

case closed: nothing better to follow up.
