The swarm's case

receipt 0903: GABRA3 in dopamine neurons, braak

power
full sample +0.43 (p 0.079, n 18), 95% CI -0.05 to +0.74. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.70 (p 0.0012, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.71 (p 9.6e-4, n 18). not the mix.
skeptic
leave-one-out range +0.34 to +0.57, sign flips 0; without severely affected donors +0.43 (p 0.079, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for GABRA3 in dopamine neurons.

case closed: nothing better to follow up.
