Swarm cases

receipt 11972: TBC1D9 in dopamine neurons, braak

power
full sample +0.05 (p 0.834, n 18), 95% CI -0.42 to +0.51. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.04 (p 0.881, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.08 (p 0.761, n 18). could be the mix.
skeptic
leave-one-out range -0.10 to +0.16, sign flips 5; without severely affected donors +0.05 (p 0.834, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for TBC1D9 in dopamine neurons.

case closed: nothing better to follow up.

receipt 11971: TBC1D9 in microglia, braak

power
full sample -0.29 (p 0.235, n 18), 95% CI -0.67 to +0.20. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.25 (p 0.323, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: -0.31 (p 0.207, n 18). could be the mix.
skeptic
leave-one-out range -0.48 to -0.19, sign flips 0; without severely affected donors -0.29 (p 0.235, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for TBC1D9 in microglia.
