The swarm's case

receipt 5109: MAN2B1 in microglia, braak

power
full sample +0.02 (p 0.949, n 18), 95% CI -0.45 to +0.48. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.00 (p 0.997, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: +0.15 (p 0.544, n 18). could be the mix.
skeptic
leave-one-out range -0.12 to +0.17, sign flips 5; without severely affected donors +0.02 (p 0.949, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for MAN2B1 in microglia.

case closed: nothing better to follow up.
