Swarm cases

receipt 0547: DRD4 in dopamine neurons, braak

cell type
DRD4 is not measured in dopamine neurons; looking elsewhere.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for DRD4 in dopamine neurons.

case closed: nothing better to follow up.

receipt 0067: DRD4 in dopamine neurons, resilience

power
full sample +0.19 (p 0.344, n 55), 95% CI -0.08 to +0.43. the interval is wide: not enough donors to tell.
confounder
adjusted for age, sex and PMI: +0.21 (p 0.283, n 55). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.12 (p 0.542); controlling for it: +0.22 (p 0.256, n 55). could be the mix.
skeptic
leave-one-out range +0.11 to +0.26, sign flips 0; without severely affected donors +0.15 (p 0.463, n 46). fragile.
cell type
no other cell group does better.
axis
no measure beats "differs in resilient donors (Lewy pathology, no parkinsonism)" for DRD4 in dopamine neurons.

case closed: nothing better to follow up.

receipt 0066: DRD4 in dopamine neurons, braak

power
full sample -0.02 (p 0.829, n 84), 95% CI -0.24 to +0.19. the interval sits on zero: probably nothing there.
confounder
adjusted for age, sex and PMI: -0.03 (p 0.768, n 84). does not hold up.
composition
dopamine neurons share of nuclei vs axis -0.72 (p 1.8e-14); controlling for it: -0.08 (p 0.464, n 84). could be the mix.
skeptic
leave-one-out range -0.06 to +0.01, sign flips 4; without severely affected donors +0.03 (p 0.793, n 75). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for DRD4 in dopamine neurons.

case closed: nothing better to follow up.
