Swarm cases

receipt 5988: CYP27A1 in dopamine neurons, braak

power
full sample -0.07 (p 0.781, n 18), 95% CI -0.52 to +0.41. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.12 (p 0.633, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.12 (p 0.627, n 18). could be the mix.
skeptic
leave-one-out range -0.19 to +0.03, sign flips 4; without severely affected donors -0.07 (p 0.781, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for CYP27A1 in dopamine neurons.

case closed: nothing better to follow up.

receipt 5987: CYP27A1 in oligodendrocytes, braak

power
full sample +0.04 (p 0.861, 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 0.915, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.05 (p 0.840, n 18). could be the mix.
skeptic
leave-one-out range -0.06 to +0.15, sign flips 4; without severely affected donors +0.04 (p 0.861, n 18). fragile.
cell type
no other cell group does better.
