Swarm cases

receipt 3328: ZDHHC9 in dopamine neurons, braak

power
full sample +0.12 (p 0.646, n 18), 95% CI -0.37 to +0.55. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.02 (p 0.928, 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 0.983, n 18). could be the mix.
skeptic
leave-one-out range -0.01 to +0.28, sign flips 1; without severely affected donors +0.12 (p 0.646, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for ZDHHC9 in dopamine neurons.

case closed: nothing better to follow up.

receipt 3327: ZDHHC9 in oligodendrocytes, braak

power
full sample +0.09 (p 0.722, n 18), 95% CI -0.39 to +0.53. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.10 (p 0.702, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.06 (p 0.814, n 18). could be the mix.
skeptic
leave-one-out range -0.02 to +0.23, sign flips 2; without severely affected donors +0.09 (p 0.722, n 18). fragile.
cell type
no other cell group does better.
axis
