Swarm cases

receipt 3185: CD55 in dopamine neurons, braak

power
full sample +0.03 (p 0.901, n 18), 95% CI -0.44 to +0.49. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.00 (p 0.997, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.04 (p 0.881, n 18). could be the mix.
skeptic
leave-one-out range -0.07 to +0.19, sign flips 6; without severely affected donors +0.03 (p 0.901, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for CD55 in dopamine neurons.

case closed: nothing better to follow up.
