Swarm cases

receipt 7539: XIAP in dopamine neurons, braak

power
full sample -0.04 (p 0.888, n 18), 95% CI -0.49 to +0.44. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.04 (p 0.874, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.13 (p 0.597, n 18). could be the mix.
skeptic
leave-one-out range -0.16 to +0.08, sign flips 4; without severely affected donors -0.04 (p 0.888, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for XIAP in dopamine neurons.

case closed: nothing better to follow up.
