Swarm cases

receipt 15778: ABCC4 in dopamine neurons, braak

power
full sample +0.15 (p 0.549, n 18), 95% CI -0.34 to +0.58. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.08 (p 0.761, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.17 (p 0.493, n 18). could be the mix.
skeptic
leave-one-out range +0.07 to +0.28, sign flips 0; without severely affected donors +0.15 (p 0.549, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for ABCC4 in dopamine neurons.

case closed: nothing better to follow up.

receipt 15777: ABCC4 in microglia, braak

power
full sample +0.02 (p 0.935, n 18), 95% CI -0.45 to +0.48. the interval is wide: not enough donors to tell.

adjusted for sex: +0.02 (p 0.949, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: +0.18 (p 0.465, n 18). could be the mix.
skeptic
leave-one-out range -0.08 to +0.19, sign flips 7; without severely affected donors +0.02 (p 0.935, n 18). fragile.
cell type
