Swarm cases

receipt 9980: FGF8 in dopamine neurons, braak

power
full sample -0.32 (p 0.198, n 18), 95% CI -0.68 to +0.17. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.31 (p 0.214, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.57 (p 0.014, n 18). not the mix.
skeptic
leave-one-out range -0.46 to -0.23, sign flips 0; without severely affected donors -0.32 (p 0.198, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for FGF8 in dopamine neurons.

case closed: nothing better to follow up.
