receipt 3004: PROK2 in dopamine neurons, braak

power
full sample +0.22 (p 0.389, n 18), 95% CI -0.28 to +0.62. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.22 (p 0.389, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.35 (p 0.150, n 18). could be the mix.
skeptic
leave-one-out range +0.11 to +0.36, sign flips 0; without severely affected donors +0.22 (p 0.389, n 18). fragile.
cell type
strongest in astrocytes: +0.59 (p 0.0092, n 18) vs +0.22 in dopamine neurons. proposing astrocytes.
axis
