Swarm cases

receipt 7197: LRPPRC in dopamine neurons, braak

power
full sample +0.37 (p 0.130, n 18), 95% CI -0.12 to +0.71. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.36 (p 0.145, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.38 (p 0.116, n 18). could be the mix.
skeptic
leave-one-out range +0.28 to +0.54, sign flips 0; without severely affected donors +0.37 (p 0.130, n 18). fragile.
cell type
strongest in OPCs: +0.70 (p 0.0011, n 18) vs +0.37 in dopamine neurons. proposing OPCs.
axis
no measure beats "tracks Braak Lewy-body stage" for LRPPRC in dopamine neurons.

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