The swarm's case

receipt 9517: FNIP1 in oligodendrocytes, braak

power
full sample +0.17 (p 0.509, n 18), 95% CI -0.33 to +0.59. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.19 (p 0.439, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.27 (p 0.273, n 18). could be the mix.
skeptic
leave-one-out range +0.05 to +0.30, sign flips 0; without severely affected donors +0.17 (p 0.509, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for FNIP1 in oligodendrocytes.

case closed: nothing better to follow up.
