Swarm cases

receipt 14805: MPPED2 in dopamine neurons, braak

power
full sample +0.20 (p 0.429, n 18), 95% CI -0.30 to +0.61. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.20 (p 0.429, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.06 (p 0.814, n 18). could be the mix.
skeptic
leave-one-out range +0.08 to +0.31, sign flips 0; without severely affected donors +0.20 (p 0.429, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for MPPED2 in dopamine neurons.

case closed: nothing better to follow up.

receipt 14804: MPPED2 in oligodendrocytes, braak

power
full sample -0.11 (p 0.671, n 18), 95% CI -0.55 to +0.38. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.10 (p 0.702, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.16 (p 0.526, n 18). could be the mix.
skeptic
leave-one-out range -0.21 to +0.01, sign flips 3; without severely affected donors -0.11 (p 0.671, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for MPPED2 in oligodendrocytes.
