Swarm cases

receipt 9393: P2RX1 in dopamine neurons, braak

power
full sample -0.54 (p 0.019, n 18), 95% CI -0.81 to -0.10. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: -0.50 (p 0.033, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.61 (p 0.0075, n 18). not the mix.
skeptic
leave-one-out range -0.72 to -0.49, sign flips 0; without severely affected donors -0.54 (p 0.019, n 18). robust.
cell type
strongest in oligodendrocytes: -0.59 (p 0.0099, n 18) vs -0.54 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for P2RX1 in dopamine neurons.
