Swarm cases

receipt 8221: ALAS2 in dopamine neurons, braak

power
full sample +0.03 (p 0.894, n 18), 95% CI -0.44 to +0.49. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.06 (p 0.807, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.12 (p 0.640, n 18). could be the mix.
skeptic
leave-one-out range -0.08 to +0.16, sign flips 5; without severely affected donors +0.03 (p 0.894, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for ALAS2 in dopamine neurons.

case closed: nothing better to follow up.
