Swarm cases

receipt 10046: SEMA6A in dopamine neurons, braak

power
full sample +0.03 (p 0.908, n 18), 95% CI -0.44 to +0.49. 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: +0.04 (p 0.888, n 18). could be the mix.
skeptic
leave-one-out range -0.07 to +0.16, sign flips 7; without severely affected donors +0.03 (p 0.908, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for SEMA6A in dopamine neurons.

case closed: nothing better to follow up.

receipt 10045: SEMA6A in oligodendrocytes, braak

power
full sample +0.19 (p 0.460, n 18), 95% CI -0.31 to +0.60. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.18 (p 0.487, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.15 (p 0.561, n 18). could be the mix.
skeptic
leave-one-out range +0.08 to +0.33, sign flips 0; without severely affected donors +0.19 (p 0.460, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for SEMA6A in oligodendrocytes.
