Swarm cases

receipt 8320: APEX1 in dopamine neurons, braak

power
full sample +0.36 (p 0.137, n 18), 95% CI -0.12 to +0.71. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.34 (p 0.170, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.39 (p 0.107, n 18). could be the mix.
skeptic
leave-one-out range +0.29 to +0.43, sign flips 0; without severely affected donors +0.36 (p 0.137, n 18). fragile.
cell type
strongest in microglia: +0.64 (p 0.0040, n 18) vs +0.36 in dopamine neurons. proposing microglia.
axis
no measure beats "tracks Braak Lewy-body stage" for APEX1 in dopamine neurons.
