Swarm cases

receipt 12697: OR2L13 in dopamine neurons, braak

power
full sample +0.21 (p 0.403, n 18), 95% CI -0.28 to +0.62. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.21 (p 0.393, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.23 (p 0.360, n 18). could be the mix.
skeptic
leave-one-out range +0.11 to +0.33, sign flips 0; without severely affected donors +0.21 (p 0.403, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for OR2L13 in dopamine neurons.

case closed: nothing better to follow up.

receipt 12696: OR2L13 in oligodendrocytes, braak

power
full sample +0.11 (p 0.671, n 18), 95% CI -0.38 to +0.55. the interval is wide: not enough donors to tell.

composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.06 (p 0.827, n 18). could be the mix.
skeptic
leave-one-out range -0.02 to +0.27, sign flips 1; without severely affected donors +0.11 (p 0.671, n 18). fragile.
