Swarm cases

receipt 0449: CLK2 in dopamine neurons, braak

power
full sample -0.11 (p 0.664, n 18), 95% CI -0.55 to +0.38. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.11 (p 0.664, 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 0.555, n 18). could be the mix.
skeptic
leave-one-out range -0.23 to +0.00, 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 CLK2 in dopamine neurons.

case closed: nothing better to follow up.

receipt 0448: CLK2 in astrocytes, braak

power
full sample +0.04 (p 0.881, n 18), 95% CI -0.44 to +0.50. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.11 (p 0.671, n 18). does not hold up.
composition
astrocytes share of nuclei vs axis -0.21 (p 0.413); controlling for it: +0.10 (p 0.702, n 18). could be the mix.
skeptic
leave-one-out range -0.07 to +0.19, sign flips 6; without severely affected donors +0.04 (p 0.881, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for CLK2 in astrocytes.
