The swarm's case

receipt 13405: ATP5PB in dopamine neurons, braak

power
full sample +0.57 (p 0.013, n 18), 95% CI +0.14 to +0.82. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: +0.57 (p 0.014, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.57 (p 0.013, n 18). not the mix.
skeptic
leave-one-out range +0.51 to +0.71, sign flips 0; without severely affected donors +0.57 (p 0.013, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for ATP5PB in dopamine neurons.

case closed: nothing better to follow up.
