The swarm's case

receipt 12239: STX12 in dopamine neurons, braak

power
full sample +0.47 (p 0.049, n 18), 95% CI +0.01 to +0.77. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: +0.48 (p 0.045, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.51 (p 0.032, n 18). not the mix.
skeptic
leave-one-out range +0.39 to +0.57, sign flips 0; without severely affected donors +0.47 (p 0.049, n 18). robust.
cell type
strongest in astrocytes: -0.75 (p 3.7e-4, n 18) vs +0.47 in dopamine neurons. proposing astrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for STX12 in dopamine neurons.
