Swarm cases

receipt 0592: SCN1A in dopamine neurons, braak

power
full sample +0.38 (p 0.116, n 18), 95% CI -0.10 to +0.72. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.38 (p 0.116, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.42 (p 0.080, n 18). could be the mix.
skeptic
leave-one-out range +0.31 to +0.50, sign flips 0; without severely affected donors +0.38 (p 0.116, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for SCN1A in dopamine neurons.

case closed: nothing better to follow up.

receipt 0135: SCN1A in oligodendrocytes, braak

power
full sample -0.09 (p 0.418, n 84), 95% CI -0.30 to +0.13. the interval sits on zero: probably nothing there.
confounder
adjusted for age, sex and PMI: -0.07 (p 0.518, n 84). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.09 (p 0.422); controlling for it: -0.08 (p 0.472, n 84). could be the mix.
skeptic
leave-one-out range -0.12 to -0.06, sign flips 0; without severely affected donors +0.04 (p 0.743, n 75). fragile.
cell type
strongest in GABA neurons: +0.31 (p 0.0040, n 84) vs -0.09 in oligodendrocytes. proposing GABA neurons.
axis
no measure beats "tracks Braak Lewy-body stage" for SCN1A in oligodendrocytes.
