Swarm cases

receipt 3409: PDE1C in dopamine neurons, braak

power
full sample +0.02 (p 0.949, n 18), 95% CI -0.45 to +0.48. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.02 (p 0.949, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.01 (p 0.976, n 18). could be the mix.
skeptic
leave-one-out range -0.13 to +0.10, sign flips 4; without severely affected donors +0.02 (p 0.949, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for PDE1C in dopamine neurons.

case closed: nothing better to follow up.

receipt 3408: PDE1C in oligodendrocytes, braak

power
full sample +0.11 (p 0.664, n 18), 95% CI -0.38 to +0.55. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.09 (p 0.728, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.20 (p 0.418, n 18). could be the mix.
skeptic
leave-one-out range -0.02 to +0.23, sign flips 1; without severely affected donors +0.11 (p 0.664, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for PDE1C in oligodendrocytes.
