The swarm's case

receipt 3687: EEF2K in astrocytes, braak

power
full sample +0.12 (p 0.633, n 18), 95% CI -0.37 to +0.56. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.06 (p 0.814, n 18). does not hold up.
composition
astrocytes share of nuclei vs axis -0.21 (p 0.413); controlling for it: +0.16 (p 0.521, n 18). could be the mix.
skeptic
leave-one-out range -0.01 to +0.23, sign flips 2; without severely affected donors +0.12 (p 0.633, n 18). fragile.
cell type
strongest in microglia: -0.75 (p 3.5e-4, n 18) vs +0.12 in astrocytes. proposing microglia.
axis
no measure beats "tracks Braak Lewy-body stage" for EEF2K in astrocytes.
