Swarm cases

receipt 12231: GYPA in dopamine neurons, braak

power
full sample +0.48 (p 0.043, n 18), 95% CI +0.02 to +0.77. the interval excludes zero: something may be there, smaller than a half can see.
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 0.016, n 18). not the mix.
skeptic
leave-one-out range +0.43 to +0.67, sign flips 0; without severely affected donors +0.48 (p 0.043, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for GYPA in dopamine neurons.

case closed: nothing better to follow up.
