Swarm cases

receipt 7201: PTGER3 in dopamine neurons, braak

power
full sample +0.42 (p 0.084, n 18), 95% CI -0.06 to +0.74. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.39 (p 0.107, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.44 (p 0.070, n 18). could be the mix.
skeptic
leave-one-out range +0.34 to +0.60, sign flips 0; without severely affected donors +0.42 (p 0.084, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for PTGER3 in dopamine neurons.

case closed: nothing better to follow up.
