Swarm cases

receipt 5474: PCDH9 in dopamine neurons, braak

power
full sample -0.00 (p 0.997, n 18), 95% CI -0.47 to +0.47. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.00 (p 0.997, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.15 (p 0.549, n 18). could be the mix.
skeptic
leave-one-out range -0.14 to +0.11, sign flips 8; without severely affected donors -0.00 (p 0.997, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for PCDH9 in dopamine neurons.

case closed: nothing better to follow up.

receipt 5473: PCDH9 in oligodendrocytes, braak

power
full sample +0.34 (p 0.170, n 18), 95% CI -0.15 to +0.70. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.32 (p 0.201, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.49 (p 0.040, n 18). not the mix.
skeptic
leave-one-out range +0.25 to +0.48, sign flips 0; without severely affected donors +0.34 (p 0.170, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for PCDH9 in oligodendrocytes.
