Swarm cases

receipt 10026: TPK1 in dopamine neurons, braak

power
full sample +0.39 (p 0.105, n 18), 95% CI -0.09 to +0.73. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.33 (p 0.176, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.34 (p 0.161, n 18). could be the mix.
skeptic
leave-one-out range +0.31 to +0.60, sign flips 0; without severely affected donors +0.39 (p 0.105, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for TPK1 in dopamine neurons.

case closed: nothing better to follow up.

receipt 10025: TPK1 in microglia, braak

power
full sample -0.03 (p 0.908, n 18), 95% CI -0.49 to +0.44. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.09 (p 0.715, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: -0.12 (p 0.640, n 18). could be the mix.
skeptic
leave-one-out range -0.14 to +0.07, sign flips 5; without severely affected donors -0.03 (p 0.908, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for TPK1 in microglia.
