receipt 3071: S100A9 in dopamine neurons, braak

power
full sample -0.00 (p 0.990, n 18), 95% CI -0.47 to +0.46. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.08 (p 0.761, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.08 (p 0.761, n 18). could be the mix.
skeptic
leave-one-out range -0.15 to +0.09, sign flips 13; without severely affected donors -0.00 (p 0.990, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for S100A9 in dopamine neurons.

case closed: nothing better to follow up.
