The swarm's case

receipt 8056: NLGN1 in oligodendrocytes, braak

power
full sample +0.06 (p 0.800, n 18), 95% CI -0.42 to +0.52. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.13 (p 0.621, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.15 (p 0.555, n 18). could be the mix.
skeptic
leave-one-out range -0.05 to +0.17, sign flips 3; without severely affected donors +0.06 (p 0.800, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for NLGN1 in oligodendrocytes.

case closed: nothing better to follow up.
