Swarm cases

receipt 10172: FGA in dopamine neurons, braak

power
full sample +0.38 (p 0.123, n 18), 95% CI -0.11 to +0.72. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.38 (p 0.118, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.47 (p 0.049, n 18). not the mix.
skeptic
leave-one-out range +0.30 to +0.50, sign flips 0; without severely affected donors +0.38 (p 0.123, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for FGA in dopamine neurons.

case closed: nothing better to follow up.
