The swarm's case

receipt 8031: SYK in microglia, braak

power
full sample +0.36 (p 0.145, n 18), 95% CI -0.13 to +0.71. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.34 (p 0.164, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: +0.34 (p 0.161, n 18). could be the mix.
skeptic
leave-one-out range +0.29 to +0.56, sign flips 0; without severely affected donors +0.36 (p 0.145, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for SYK in microglia.

case closed: nothing better to follow up.
