Swarm cases

receipt 5689: PER2 in dopamine neurons, braak

power
full sample -0.11 (p 0.671, n 18), 95% CI -0.55 to +0.38. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.16 (p 0.521, 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 0.621, n 18). could be the mix.
skeptic
leave-one-out range -0.27 to +0.02, sign flips 1; without severely affected donors -0.11 (p 0.671, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for PER2 in dopamine neurons.

case closed: nothing better to follow up.
