Swarm cases

receipt 8857: GZMB in dopamine neurons, braak

power
full sample -0.02 (p 0.935, n 18), 95% CI -0.48 to +0.45. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.01 (p 0.983, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.09 (p 0.735, n 18). could be the mix.
skeptic
leave-one-out range -0.17 to +0.11, sign flips 6; without severely affected donors -0.02 (p 0.935, n 18). fragile.
cell type
strongest in astrocytes: -0.66 (p 0.0028, n 18) vs -0.02 in dopamine neurons. proposing astrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for GZMB in dopamine neurons.

case closed: every proposal failed a challenge.
