Swarm cases

receipt 4359: ARRB2 in dopamine neurons, braak

power
full sample -0.45 (p 0.060, n 18), 95% CI -0.76 to +0.02. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.43 (p 0.075, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.52 (p 0.026, n 18). not the mix.
skeptic
leave-one-out range -0.56 to -0.38, sign flips 0; without severely affected donors -0.45 (p 0.060, n 18). robust.
cell type
strongest in OPCs: -0.60 (p 0.0086, n 18) vs -0.45 in dopamine neurons. proposing OPCs.
axis
no measure beats "tracks Braak Lewy-body stage" for ARRB2 in dopamine neurons.

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

receipt 4358: ARRB2 in microglia, braak

power
full sample -0.10 (p 0.696, n 18), 95% CI -0.54 to +0.39. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.09 (p 0.709, n 18). does not hold up.
composition
microglia share of nuclei vs axis -0.11 (p 0.652); controlling for it: -0.05 (p 0.854, n 18). could be the mix.
skeptic
leave-one-out range -0.26 to +0.03, sign flips 1; without severely affected donors -0.10 (p 0.696, n 18). fragile.
cell type
strongest in OPCs: -0.60 (p 0.0086, n 18) vs -0.10 in microglia. proposing OPCs.
axis
no measure beats "tracks Braak Lewy-body stage" for ARRB2 in microglia.
