Swarm cases

receipt 0531: DRD2 in dopamine neurons, braak

power
full sample -0.16 (p 0.515, n 18), 95% CI -0.59 to +0.33. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.19 (p 0.450, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.30 (p 0.228, n 18). could be the mix.
skeptic
leave-one-out range -0.30 to -0.06, sign flips 0; without severely affected donors -0.16 (p 0.515, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for DRD2 in dopamine neurons.

case closed: nothing better to follow up.

receipt 0040: DRD2 in dopamine neurons, resilience

power
full sample +0.09 (p 0.659, n 55), 95% CI -0.18 to +0.34. the interval is wide: not enough donors to tell.
confounder
adjusted for age, sex and PMI: +0.10 (p 0.614, n 55). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.12 (p 0.542); controlling for it: +0.10 (p 0.628, n 55). could be the mix.
skeptic
leave-one-out range +0.00 to +0.19, sign flips 1; without severely affected donors +0.06 (p 0.767, n 46). fragile.
cell type
no other cell group does better.
axis
no measure beats "differs in resilient donors (Lewy pathology, no parkinsonism)" for DRD2 in dopamine neurons.

case closed: nothing better to follow up.

receipt 0039: DRD2 in dopamine neurons, braak

power
full sample -0.08 (p 0.480, n 84), 95% CI -0.29 to +0.14. the interval sits on zero: probably nothing there.
confounder
adjusted for age, sex and PMI: -0.09 (p 0.398, n 84). does not hold up.
composition
dopamine neurons share of nuclei vs axis -0.72 (p 1.8e-14); controlling for it: -0.07 (p 0.519, n 84). could be the mix.
skeptic
leave-one-out range -0.11 to -0.05, sign flips 0; without severely affected donors -0.03 (p 0.770, n 75). fragile.
cell type
strongest in oligodendrocytes: -0.30 (p 0.0049, n 84) vs -0.08 in dopamine neurons. proposing oligodendrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for DRD2 in dopamine neurons.

follow-up confirmed in ventral tegmental area.
