Swarm cases

receipt 15522: KLF13 in dopamine neurons, braak

power
full sample -0.43 (p 0.077, n 18), 95% CI -0.75 to +0.05. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.52 (p 0.027, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.63 (p 0.0053, n 18). not the mix.
skeptic
leave-one-out range -0.51 to -0.36, sign flips 0; without severely affected donors -0.43 (p 0.077, n 18). robust.
cell type
strongest in oligodendrocytes: -0.73 (p 5.3e-4, n 18) vs -0.43 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for KLF13 in dopamine neurons.

follow-up registered; not confirmed in substantia nigra, an independent cohort.
follow-up KLF13 · oligodendrocytes · braak: substantia nigra, an independent cohort (Parkinson's or LBD vs controls) -0.63 p 0.026 (needs p < 1.5e-4)

receipt 15521: KLF13 in oligodendrocytes, braak

power
full sample -0.73 (p 5.3e-4, n 18), 95% CI -0.89 to -0.41. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: -0.70 (p 0.0011, n 18). holds up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.76 (p 2.7e-4, n 18). not the mix.
skeptic
leave-one-out range -0.79 to -0.70, sign flips 0; without severely affected donors -0.73 (p 5.3e-4, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for KLF13 in oligodendrocytes.

case closed: nothing better to follow up.
