The swarm's case

receipt 16572: OSBPL6 in astrocytes, braak

power
full sample +0.18 (p 0.465, n 18), 95% CI -0.31 to +0.60. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.19 (p 0.455, n 18). does not hold up.
composition
astrocytes share of nuclei vs axis -0.21 (p 0.413); controlling for it: +0.20 (p 0.429, n 18). could be the mix.
skeptic
leave-one-out range +0.06 to +0.31, sign flips 0; without severely affected donors +0.18 (p 0.465, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for OSBPL6 in astrocytes.

case closed: nothing better to follow up.
