Swarm cases

receipt 1152: ALDH8A1 in dopamine neurons, braak

power
full sample -0.36 (p 0.137, n 18), 95% CI -0.71 to +0.12. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.36 (p 0.148, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.38 (p 0.123, n 18). could be the mix.
skeptic
leave-one-out range -0.43 to -0.29, sign flips 0; without severely affected donors -0.36 (p 0.137, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for ALDH8A1 in dopamine neurons.

case closed: nothing better to follow up.

receipt 1151: ALDH8A1 in oligodendrocytes, braak

power
full sample -0.42 (p 0.082, n 18), 95% CI -0.74 to +0.06. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.41 (p 0.091, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.34 (p 0.167, n 18). could be the mix.
skeptic
leave-one-out range -0.48 to -0.32, sign flips 0; without severely affected donors -0.42 (p 0.082, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for ALDH8A1 in oligodendrocytes.
