The swarm's case

receipt 0575: ADRB1 in astrocytes, braak

power
full sample -0.21 (p 0.413, n 18), 95% CI -0.61 to +0.29. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.20 (p 0.434, n 18). does not hold up.
composition
astrocytes share of nuclei vs axis -0.21 (p 0.413); controlling for it: -0.24 (p 0.341, n 18). could be the mix.
skeptic
leave-one-out range -0.35 to -0.08, sign flips 0; without severely affected donors -0.21 (p 0.413, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for ADRB1 in astrocytes.

case closed: nothing better to follow up.
