The swarm's case

receipt 1654: GOLGA8J in dopamine neurons, braak

power
full sample -0.45 (p 0.063, n 18), 95% CI -0.76 to +0.03. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.45 (p 0.063, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.39 (p 0.111, n 18). could be the mix.
skeptic
leave-one-out range -0.63 to -0.39, sign flips 0; without severely affected donors -0.45 (p 0.063, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for GOLGA8J in dopamine neurons.

case closed: nothing better to follow up.
