Swarm cases

receipt 9215: PAH in dopamine neurons, braak

power
full sample +0.22 (p 0.374, n 18), 95% CI -0.27 to +0.62. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.25 (p 0.323, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.06 (p 0.820, n 18). could be the mix.
skeptic
leave-one-out range +0.13 to +0.38, sign flips 0; without severely affected donors +0.22 (p 0.374, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for PAH in dopamine neurons.

case closed: nothing better to follow up.
