The swarm's case

receipt 16624: LAYN in oligodendrocytes, braak

power
full sample -0.29 (p 0.246, n 18), 95% CI -0.67 to +0.21. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.28 (p 0.261, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.29 (p 0.235, n 18). could be the mix.
skeptic
leave-one-out range -0.43 to -0.18, sign flips 0; without severely affected donors -0.29 (p 0.246, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for LAYN in oligodendrocytes.

case closed: nothing better to follow up.
