The swarm's case

receipt 3010: SLC1A2 in astrocytes, braak

power
full sample +0.30 (p 0.232, n 18), 95% CI -0.20 to +0.67. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.31 (p 0.204, n 18). does not hold up.
composition
astrocytes share of nuclei vs axis -0.21 (p 0.413); controlling for it: +0.31 (p 0.204, n 18). could be the mix.
skeptic
leave-one-out range +0.21 to +0.40, sign flips 0; without severely affected donors +0.30 (p 0.232, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for SLC1A2 in astrocytes.

case closed: nothing better to follow up.
