receipt 4995: PGF in dopamine neurons, braak

power
full sample -0.54 (p 0.019, n 18), 95% CI -0.81 to -0.10. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: -0.56 (p 0.016, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.66 (p 0.0030, n 18). not the mix.
skeptic
leave-one-out range -0.66 to -0.48, sign flips 0; without severely affected donors -0.54 (p 0.019, n 18). robust.
cell type
strongest in astrocytes: -0.61 (p 0.0069, n 18) vs -0.54 in dopamine neurons. proposing astrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for PGF in dopamine neurons.
