The swarm's case

receipt 2097: SNX18 in microglia, braak

power
full sample -0.02 (p 0.928, n 18), 95% CI -0.48 to +0.45. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.09 (p 0.709, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: -0.09 (p 0.722, n 18). could be the mix.
skeptic
leave-one-out range -0.18 to +0.08, sign flips 8; without severely affected donors -0.02 (p 0.928, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for SNX18 in microglia.

case closed: nothing better to follow up.
