Swarm cases

receipt 4315: TTBK1 in dopamine neurons, braak

power
full sample -0.36 (p 0.145, n 18), 95% CI -0.71 to +0.13. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.38 (p 0.120, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.49 (p 0.040, n 18). not the mix.
skeptic
leave-one-out range -0.47 to -0.27, sign flips 0; without severely affected donors -0.36 (p 0.145, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for TTBK1 in dopamine neurons.

case closed: nothing better to follow up.

receipt 4314: TTBK1 in oligodendrocytes, braak

power
full sample -0.31 (p 0.207, n 18), 95% CI -0.68 to +0.18. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.38 (p 0.125, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.21 (p 0.408, n 18). could be the mix.
skeptic
leave-one-out range -0.51 to -0.24, sign flips 0; without severely affected donors -0.31 (p 0.207, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for TTBK1 in oligodendrocytes.

case closed: nothing better to follow up.
