Swarm cases

receipt 3437: ABCD2 in dopamine neurons, braak

power
full sample +0.21 (p 0.393, n 18), 95% CI -0.28 to +0.62. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.23 (p 0.365, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.28 (p 0.261, n 18). could be the mix.
skeptic
leave-one-out range +0.13 to +0.38, sign flips 0; without severely affected donors +0.21 (p 0.393, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for ABCD2 in dopamine neurons.

case closed: nothing better to follow up.

receipt 3436: ABCD2 in astrocytes, braak

adjusted for sex: -0.14 (p 0.579, n 18). does not hold up.
composition
astrocytes share of nuclei vs axis -0.21 (p 0.413); controlling for it: -0.02 (p 0.928, n 18). could be the mix.
skeptic
leave-one-out range -0.26 to -0.02, sign flips 0; without severely affected donors -0.13 (p 0.621, n 18). fragile.
cell type
