receipt 12983: MAP2K2 in dopamine neurons, braak

power
full sample -0.01 (p 0.969, n 18), 95% CI -0.47 to +0.46. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.05 (p 0.834, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.14 (p 0.585, n 18). could be the mix.
skeptic
leave-one-out range -0.09 to +0.13, sign flips 5; without severely affected donors -0.01 (p 0.969, n 18). fragile.
cell type
strongest in oligodendrocytes: -0.72 (p 8.2e-4, n 18) vs -0.01 in dopamine neurons. proposing oligodendrocytes.
