The swarm's case

receipt 11570: SOD3 in dopamine neurons, braak

power
full sample -0.42 (p 0.082, n 18), 95% CI -0.74 to +0.06. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.47 (p 0.051, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.56 (p 0.015, n 18). not the mix.
skeptic
leave-one-out range -0.57 to -0.35, sign flips 0; without severely affected donors -0.42 (p 0.082, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for SOD3 in dopamine neurons.

case closed: nothing better to follow up.
