Swarm cases

receipt 17272: KCNE4 in dopamine neurons, braak

power
full sample +0.36 (p 0.145, n 18), 95% CI -0.13 to +0.71. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.35 (p 0.150, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.41 (p 0.093, n 18). could be the mix.
skeptic
leave-one-out range +0.26 to +0.50, sign flips 0; without severely affected donors +0.36 (p 0.145, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for KCNE4 in dopamine neurons.

case closed: nothing better to follow up.

receipt 17271: KCNE4 in astrocytes, braak

power
full sample +0.05 (p 0.840, n 18), 95% CI -0.43 to +0.51. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.10 (p 0.683, n 18). does not hold up.
composition
astrocytes share of nuclei vs axis -0.21 (p 0.413); controlling for it: +0.06 (p 0.827, n 18). could be the mix.
skeptic
leave-one-out range -0.04 to +0.16, sign flips 4; without severely affected donors +0.05 (p 0.840, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for KCNE4 in astrocytes.
