Swarm cases

receipt 3393: STARD9 in dopamine neurons, braak

power
full sample -0.40 (p 0.097, n 18), 95% CI -0.73 to +0.08. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.43 (p 0.075, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.43 (p 0.075, n 18). could be the mix.
skeptic
leave-one-out range -0.51 to -0.34, sign flips 0; without severely affected donors -0.40 (p 0.097, n 18). robust.
cell type
strongest in oligodendrocytes: -0.59 (p 0.0096, n 18) vs -0.40 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for STARD9 in dopamine neurons.

follow-up registered; not confirmed in substantia nigra, an independent cohort.

receipt 3392: STARD9 in oligodendrocytes, braak

power
full sample -0.59 (p 0.0096, n 18), 95% CI -0.83 to -0.17. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: -0.55 (p 0.018, n 18). holds up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.61 (p 0.0069, n 18). not the mix.
skeptic
leave-one-out range -0.72 to -0.53, sign flips 0; without severely affected donors -0.59 (p 0.0096, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for STARD9 in oligodendrocytes.

case closed: nothing better to follow up.
