receipt 6066: BBS5 in dopamine neurons, braak

power
full sample -0.04 (p 0.867, n 18), 95% CI -0.50 to +0.43. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.00 (p 0.990, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.07 (p 0.787, n 18). could be the mix.
skeptic
leave-one-out range -0.18 to +0.05, sign flips 4; without severely affected donors -0.04 (p 0.867, n 18). fragile.
cell type
strongest in astrocytes: -0.68 (p 0.0018, n 18) vs -0.04 in dopamine neurons. proposing astrocytes.
