receipt 2106: PIEZO1 in dopamine neurons, braak

power
full sample -0.43 (p 0.072, n 18), 95% CI -0.75 to +0.04. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.47 (p 0.049, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.64 (p 0.0040, n 18). not the mix.
skeptic
leave-one-out range -0.56 to -0.36, sign flips 0; without severely affected donors -0.43 (p 0.072, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for PIEZO1 in dopamine neurons.

case closed: nothing better to follow up.
