Swarm cases

receipt 2599: GPX4 in dopamine neurons, braak

power
full sample +0.37 (p 0.132, n 18), 95% CI -0.12 to +0.71. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.30 (p 0.221, 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 +0.28 to +0.48, sign flips 0; without severely affected donors +0.37 (p 0.132, n 18). fragile.
cell type
strongest in OPCs: +0.65 (p 0.0036, n 18) vs +0.37 in dopamine neurons. proposing OPCs.
axis
no measure beats "tracks Braak Lewy-body stage" for GPX4 in dopamine neurons.

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