Swarm cases

receipt 13053: ZDHHC20 in dopamine neurons, braak

power
full sample -0.07 (p 0.774, n 18), 95% CI -0.52 to +0.41. 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
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.02 (p 0.928, n 18). could be the mix.
skeptic
leave-one-out range -0.22 to +0.04, sign flips 3; without severely affected donors -0.07 (p 0.774, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for ZDHHC20 in dopamine neurons.

case closed: nothing better to follow up.

receipt 13052: ZDHHC20 in oligodendrocytes, braak

power
full sample +0.06 (p 0.820, n 18), 95% CI -0.42 to +0.51. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.06 (p 0.820, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.19 (p 0.439, n 18). could be the mix.
skeptic
leave-one-out range -0.08 to +0.17, sign flips 4; without severely affected donors +0.06 (p 0.820, n 18). fragile.
cell type
no other cell group does better.
axis
