receipt 16735: MRS2 in dopamine neurons, braak

power
full sample +0.01 (p 0.983, n 18), 95% CI -0.46 to +0.47. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.06 (p 0.807, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.14 (p 0.585, n 18). could be the mix.
skeptic
leave-one-out range -0.12 to +0.10, sign flips 8; without severely affected donors +0.01 (p 0.983, n 18). fragile.
cell type
strongest in microglia: -0.67 (p 0.0024, n 18) vs +0.01 in dopamine neurons. proposing microglia.
axis
no measure beats "tracks Braak Lewy-body stage" for MRS2 in dopamine neurons.

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