Swarm cases

receipt 14815: GRK2 in dopamine neurons, braak

power
full sample -0.53 (p 0.024, n 18), 95% CI -0.80 to -0.08. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: -0.52 (p 0.027, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.60 (p 0.0083, n 18). not the mix.
skeptic
leave-one-out range -0.64 to -0.47, sign flips 0; without severely affected donors -0.53 (p 0.024, n 18). robust.
cell type
strongest in OPCs: -0.65 (p 0.0036, n 18) vs -0.53 in dopamine neurons. proposing OPCs.
axis
no measure beats "tracks Braak Lewy-body stage" for GRK2 in dopamine neurons.

follow-up registered; not confirmed in substantia nigra, an independent cohort.
