Swarm cases

receipt 12934: TBC1D4 in dopamine neurons, braak

power
full sample +0.13 (p 0.621, n 18), 95% CI -0.36 to +0.56. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.13 (p 0.621, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.09 (p 0.728, n 18). could be the mix.
skeptic
leave-one-out range -0.01 to +0.23, sign flips 1; without severely affected donors +0.13 (p 0.621, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for TBC1D4 in dopamine neurons.

case closed: nothing better to follow up.

receipt 12933: TBC1D4 in microglia, braak

power
full sample -0.15 (p 0.555, n 18), 95% CI -0.58 to +0.34. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.28 (p 0.254, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: -0.24 (p 0.346, n 18). could be the mix.
skeptic
leave-one-out range -0.26 to -0.03, sign flips 0; without severely affected donors -0.15 (p 0.555, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for TBC1D4 in microglia.
