Swarm cases

receipt 12282: NAV2 in oligodendrocytes, braak

power
full sample -0.63 (p 0.0053, n 18), 95% CI -0.85 to -0.23. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: -0.68 (p 0.0018, n 18). holds up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.73 (p 5.6e-4, n 18). not the mix.
skeptic
leave-one-out range -0.72 to -0.58, sign flips 0; without severely affected donors -0.63 (p 0.0053, n 18). robust.
cell type
strongest in dopamine neurons: -0.73 (p 5.9e-4, n 18) vs -0.63 in oligodendrocytes. proposing dopamine neurons.
axis
no measure beats "tracks Braak Lewy-body stage" for NAV2 in oligodendrocytes.
