Swarm cases

receipt 8288: MAPK7 in dopamine neurons, braak

power
full sample -0.44 (p 0.069, n 18), 95% CI -0.75 to +0.04. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.39 (p 0.111, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.54 (p 0.020, n 18). not the mix.
skeptic
leave-one-out range -0.61 to -0.37, sign flips 0; without severely affected donors -0.44 (p 0.069, n 18). robust.
cell type
strongest in microglia: -0.70 (p 0.0013, n 18) vs -0.44 in dopamine neurons. proposing microglia.
axis
no measure beats "tracks Braak Lewy-body stage" for MAPK7 in dopamine neurons.
