The swarm's case

receipt 5366: IL33 in astrocytes, braak

power
full sample +0.25 (p 0.310, n 18), 95% CI -0.24 to +0.64. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.24 (p 0.346, n 18). does not hold up.
composition
astrocytes share of nuclei vs axis -0.21 (p 0.413); controlling for it: +0.25 (p 0.310, n 18). could be the mix.
skeptic
leave-one-out range +0.15 to +0.38, sign flips 0; without severely affected donors +0.25 (p 0.310, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for IL33 in astrocytes.

case closed: nothing better to follow up.
