receipt 13433: BRK1 in dopamine neurons, braak

power
full sample +0.12 (p 0.633, n 18), 95% CI -0.37 to +0.56. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.11 (p 0.664, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.09 (p 0.735, n 18). could be the mix.
skeptic
leave-one-out range +0.01 to +0.25, sign flips 0; without severely affected donors +0.12 (p 0.633, n 18). fragile.
cell type
strongest in astrocytes: -0.76 (p 2.5e-4, n 18) vs +0.12 in dopamine neurons. proposing astrocytes.
axis
