Swarm cases

receipt 1410: ARPC2 in dopamine neurons, braak

power
full sample -0.11 (p 0.677, n 18), 95% CI -0.55 to +0.38. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.00 (p 0.997, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.07 (p 0.794, n 18). could be the mix.
skeptic
leave-one-out range -0.25 to +0.00, sign flips 1; without severely affected donors -0.11 (p 0.677, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for ARPC2 in dopamine neurons.

case closed: nothing better to follow up.
