Swarm cases

receipt 10620: SLC4A4 in dopamine neurons, braak

power
full sample +0.29 (p 0.243, n 18), 95% CI -0.20 to +0.67. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.31 (p 0.218, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.29 (p 0.235, n 18). could be the mix.
skeptic
leave-one-out range +0.23 to +0.48, sign flips 0; without severely affected donors +0.29 (p 0.243, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for SLC4A4 in dopamine neurons.

case closed: nothing better to follow up.

receipt 10619: SLC4A4 in astrocytes, braak

power
full sample +0.09 (p 0.735, n 18), 95% CI -0.40 to +0.53. the interval is wide: not enough donors to tell.

composition
astrocytes share of nuclei vs axis -0.21 (p 0.413); controlling for it: +0.14 (p 0.573, n 18). could be the mix.
skeptic
leave-one-out range -0.05 to +0.19, sign flips 3; without severely affected donors +0.09 (p 0.735, n 18). fragile.
cell type
no other cell group does better.
