Swarm cases

receipt 5330: GPI in dopamine neurons, braak

power
full sample -0.24 (p 0.328, n 18), 95% CI -0.64 to +0.25. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.21 (p 0.393, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.24 (p 0.332, n 18). could be the mix.
skeptic
leave-one-out range -0.40 to -0.16, sign flips 0; without severely affected donors -0.24 (p 0.328, n 18). fragile.
cell type
strongest in OPCs: -0.63 (p 0.0055, n 18) vs -0.24 in dopamine neurons. proposing OPCs.
axis
no measure beats "tracks Braak Lewy-body stage" for GPI in dopamine neurons.
