The swarm's case

receipt 13563: ZNF398 in dopamine neurons, braak

power
full sample -0.24 (p 0.341, n 18), 95% CI -0.63 to +0.26. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.24 (p 0.341, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.26 (p 0.289, n 18). could be the mix.
skeptic
leave-one-out range -0.39 to -0.13, sign flips 0; without severely affected donors -0.24 (p 0.341, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for ZNF398 in dopamine neurons.

case closed: nothing better to follow up.
