Swarm cases

receipt 1729: SEPSECS in dopamine neurons, braak

power
full sample +0.34 (p 0.167, n 18), 95% CI -0.15 to +0.70. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.36 (p 0.148, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.40 (p 0.099, n 18). could be the mix.
skeptic
leave-one-out range +0.25 to +0.51, sign flips 0; without severely affected donors +0.34 (p 0.167, n 18). fragile.
cell type
strongest in microglia: +0.61 (p 0.0067, n 18) vs +0.34 in dopamine neurons. proposing microglia.
axis
no measure beats "tracks Braak Lewy-body stage" for SEPSECS in dopamine neurons.

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