The swarm's case

receipt 4276: DOCK3 in dopamine neurons, braak

power
full sample +0.33 (p 0.188, n 18), 95% CI -0.17 to +0.69. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.38 (p 0.120, 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 0.105, n 18). could be the mix.
skeptic
leave-one-out range +0.26 to +0.47, sign flips 0; without severely affected donors +0.33 (p 0.188, n 18). fragile.
cell type
strongest in astrocytes: -0.66 (p 0.0031, n 18) vs +0.33 in dopamine neurons. proposing astrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for DOCK3 in dopamine neurons.
