Swarm cases

receipt 2252: TH in dopamine neurons, braak

power
full sample -0.45 (p 0.062, n 18), 95% CI -0.76 to +0.02. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.43 (p 0.075, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.45 (p 0.062, n 18). could be the mix.
skeptic
leave-one-out range -0.56 to -0.37, sign flips 0; without severely affected donors -0.45 (p 0.062, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for TH in dopamine neurons.

case closed: nothing better to follow up.
