The swarm's case

receipt 1998: WDFY1 in microglia, braak

power
full sample -0.21 (p 0.398, n 18), 95% CI -0.62 to +0.28. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.22 (p 0.379, 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 -0.33 to -0.10, sign flips 0; without severely affected donors -0.21 (p 0.398, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for WDFY1 in microglia.

case closed: nothing better to follow up.
