Swarm cases

receipt 0850: PDE7B in dopamine neurons, braak

power
full sample +0.27 (p 0.277, n 18), 95% CI -0.22 to +0.65. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.21 (p 0.398, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.24 (p 0.337, n 18). could be the mix.
skeptic
leave-one-out range +0.16 to +0.40, sign flips 0; without severely affected donors +0.27 (p 0.277, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for PDE7B in dopamine neurons.

case closed: nothing better to follow up.

receipt 0849: PDE7B in astrocytes, braak

power
full sample +0.14 (p 0.585, n 18), 95% CI -0.35 to +0.57. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.04 (p 0.861, n 18). does not hold up.
composition
astrocytes share of nuclei vs axis -0.21 (p 0.413); controlling for it: +0.08 (p 0.754, n 18). could be the mix.
skeptic
leave-one-out range +0.01 to +0.27, sign flips 0; without severely affected donors +0.14 (p 0.585, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for PDE7B in astrocytes.
