Swarm cases

receipt 0533: DRD3 in dopamine neurons, braak

power
full sample +0.23 (p 0.355, n 18), 95% CI -0.26 to +0.63. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.19 (p 0.455, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.33 (p 0.182, n 18). could be the mix.
skeptic
leave-one-out range +0.11 to +0.31, sign flips 0; without severely affected donors +0.23 (p 0.355, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for DRD3 in dopamine neurons.

case closed: nothing better to follow up.

receipt 0043: DRD3 in dopamine neurons, resilience

power
full sample -0.29 (p 0.147, n 55), 95% CI -0.51 to -0.02. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for age, sex and PMI: -0.27 (p 0.171, n 55). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.12 (p 0.542); controlling for it: -0.26 (p 0.192, n 55). could be the mix.
skeptic
leave-one-out range -0.37 to -0.21, sign flips 0; without severely affected donors -0.31 (p 0.119, n 46). fragile.
cell type
no other cell group does better.
axis
no measure beats "differs in resilient donors (Lewy pathology, no parkinsonism)" for DRD3 in dopamine neurons.

case closed: nothing better to follow up.

receipt 0042: DRD3 in dopamine neurons, braak

power
full sample +0.03 (p 0.805, n 84), 95% CI -0.19 to +0.24. the interval sits on zero: probably nothing there.
confounder
adjusted for age, sex and PMI: +0.02 (p 0.824, n 84). does not hold up.
composition
dopamine neurons share of nuclei vs axis -0.72 (p 1.8e-14); controlling for it: +0.01 (p 0.956, n 84). could be the mix.
skeptic
leave-one-out range -0.01 to +0.06, sign flips 3; without severely affected donors +0.07 (p 0.523, n 75). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for DRD3 in dopamine neurons.

case closed: nothing better to follow up.
