Swarm cases

receipt 4570: LRRC4B in dopamine neurons, braak

power
full sample -0.03 (p 0.908, n 18), 95% CI -0.49 to +0.44. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.03 (p 0.908, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.03 (p 0.915, n 18). could be the mix.
skeptic
leave-one-out range -0.19 to +0.07, sign flips 6; without severely affected donors -0.03 (p 0.908, n 18). fragile.
cell type
strongest in oligodendrocytes: -0.63 (p 0.0053, n 18) vs -0.03 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for LRRC4B in dopamine neurons.

follow-up registered; not confirmed in substantia nigra, an independent cohort.
follow-up LRRC4B · oligodendrocytes · braak: substantia nigra, an independent cohort (Parkinson's or LBD vs controls) -0.78 p 0.0059 (needs p < 4.4e-4)

receipt 4569: LRRC4B in oligodendrocytes, braak

power
full sample -0.63 (p 0.0053, n 18), 95% CI -0.85 to -0.23. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: -0.63 (p 0.0053, n 18). holds up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.59 (p 0.011, n 18). not the mix.
skeptic
leave-one-out range -0.72 to -0.57, sign flips 0; without severely affected donors -0.63 (p 0.0053, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for LRRC4B in oligodendrocytes.

case closed: nothing better to follow up.
