Swarm cases

receipt 0770: CD33 in dopamine neurons, braak

power
full sample +0.07 (p 0.781, n 18), 95% CI -0.41 to +0.52. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.07 (p 0.781, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.13 (p 0.597, n 18). could be the mix.
skeptic
leave-one-out range -0.03 to +0.18, sign flips 4; without severely affected donors +0.07 (p 0.781, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for CD33 in dopamine neurons.

case closed: nothing better to follow up.

receipt 0769: CD33 in microglia, braak

power
full sample -0.11 (p 0.658, n 18), 95% CI -0.55 to +0.37. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.09 (p 0.735, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: +0.04 (p 0.888, n 18). could be the mix.
skeptic
leave-one-out range -0.27 to +0.02, sign flips 2; without severely affected donors -0.11 (p 0.658, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for CD33 in microglia.
