The swarm's case

receipt 0715: GRIA4 in oligodendrocytes, braak

power
full sample +0.12 (p 0.633, n 18), 95% CI -0.37 to +0.56. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.19 (p 0.444, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.19 (p 0.439, n 18). could be the mix.
skeptic
leave-one-out range -0.01 to +0.23, sign flips 1; without severely affected donors +0.12 (p 0.633, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for GRIA4 in oligodendrocytes.

case closed: nothing better to follow up.
