Swarm cases

receipt 0583: CHRM3 in dopamine neurons, braak

power
full sample +0.74 (p 4.4e-4, n 18), 95% CI +0.42 to +0.90. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: +0.78 (p 1.5e-4, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.78 (p 1.6e-4, n 18). not the mix.
skeptic
leave-one-out range +0.71 to +0.91, sign flips 0; without severely affected donors +0.74 (p 4.4e-4, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for CHRM3 in dopamine neurons.

case closed: nothing better to follow up.

receipt 0125: CHRM3 in dopamine neurons, resilience

power
full sample +0.17 (p 0.377, n 55), 95% CI -0.10 to +0.42. the interval is wide: not enough donors to tell.
confounder
adjusted for age, sex and PMI: +0.19 (p 0.344, n 55). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.12 (p 0.542); controlling for it: +0.19 (p 0.333, n 55). could be the mix.
skeptic
leave-one-out range +0.11 to +0.28, sign flips 0; without severely affected donors +0.18 (p 0.374, n 46). fragile.
cell type
no other cell group does better.
axis
no measure beats "differs in resilient donors (Lewy pathology, no parkinsonism)" for CHRM3 in dopamine neurons.

case closed: nothing better to follow up.

receipt 0124: CHRM3 in dopamine neurons, braak

power
full sample -0.09 (p 0.418, n 84), 95% CI -0.30 to +0.13. the interval sits on zero: probably nothing there.
confounder
adjusted for age, sex and PMI: -0.05 (p 0.621, n 84). does not hold up.
composition
dopamine neurons share of nuclei vs axis -0.72 (p 1.8e-14); controlling for it: -0.04 (p 0.743, n 84). could be the mix.
skeptic
leave-one-out range -0.12 to -0.06, sign flips 0; without severely affected donors -0.08 (p 0.474, n 75). fragile.
cell type
strongest in glutamate neurons: +0.52 (p 3.2e-7, n 84) vs -0.09 in dopamine neurons. proposing glutamate neurons.
axis
no measure beats "tracks Braak Lewy-body stage" for CHRM3 in dopamine neurons.

follow-up confirmed in ventral tegmental area.
