Swarm cases

receipt 4245: PTCHD1 in dopamine neurons, braak

power
full sample +0.05 (p 0.847, n 18), 95% CI -0.43 to +0.50. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.03 (p 0.894, 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 0.962, n 18). could be the mix.
skeptic
leave-one-out range -0.05 to +0.16, sign flips 4; without severely affected donors +0.05 (p 0.847, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for PTCHD1 in dopamine neurons.

case closed: nothing better to follow up.

receipt 4244: PTCHD1 in astrocytes, braak

power
full sample -0.00 (p 0.990, n 18), 95% CI -0.47 to +0.46. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.01 (p 0.969, n 18). does not hold up.
composition
astrocytes share of nuclei vs axis -0.21 (p 0.413); controlling for it: -0.01 (p 0.983, n 18). could be the mix.
skeptic
leave-one-out range -0.11 to +0.13, sign flips 6; without severely affected donors -0.00 (p 0.990, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for PTCHD1 in astrocytes.
