receipt 16737: OR7A5 in dopamine neurons, braak

power
full sample +0.47 (p 0.050, n 18), 95% CI +0.00 to +0.77. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: +0.39 (p 0.114, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.47 (p 0.049, n 18). not the mix.
skeptic
leave-one-out range +0.40 to +0.55, sign flips 0; without severely affected donors +0.47 (p 0.050, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for OR7A5 in dopamine neurons.

case closed: nothing better to follow up.
