Swarm cases

receipt 13178: XAF1 in dopamine neurons, braak

power
full sample -0.14 (p 0.579, n 18), 95% CI -0.57 to +0.35. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.04 (p 0.867, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.12 (p 0.646, n 18). could be the mix.
skeptic
leave-one-out range -0.28 to -0.01, sign flips 0; without severely affected donors -0.14 (p 0.579, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for XAF1 in dopamine neurons.

case closed: nothing better to follow up.

receipt 13177: XAF1 in microglia, braak

power
full sample -0.07 (p 0.794, n 18), 95% CI -0.52 to +0.41. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.02 (p 0.935, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: -0.07 (p 0.774, n 18). could be the mix.
skeptic
leave-one-out range -0.13 to +0.08, sign flips 4; without severely affected donors -0.07 (p 0.794, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for XAF1 in microglia.
