Swarm cases

receipt 12206: GDA in dopamine neurons, braak

power
full sample +0.09 (p 0.715, n 18), 95% CI -0.39 to +0.54. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.15 (p 0.555, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.13 (p 0.603, n 18). could be the mix.
skeptic
leave-one-out range -0.02 to +0.20, sign flips 2; without severely affected donors +0.09 (p 0.715, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for GDA in dopamine neurons.

case closed: nothing better to follow up.
