receipt 7650: SRP54 in dopamine neurons, braak

power
full sample +0.27 (p 0.277, n 18), 95% CI -0.22 to +0.65. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.23 (p 0.355, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.28 (p 0.261, n 18). could be the mix.
skeptic
leave-one-out range +0.18 to +0.43, sign flips 0; without severely affected donors +0.27 (p 0.277, n 18). fragile.
cell type
strongest in astrocytes: -0.64 (p 0.0044, n 18) vs +0.27 in dopamine neurons. proposing astrocytes.
