Swarm cases

receipt 0528: CHRM1 in dopamine neurons, braak

power
full sample -0.36 (p 0.148, n 18), 95% CI -0.71 to +0.13. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.40 (p 0.103, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.57 (p 0.014, n 18). not the mix.
skeptic
leave-one-out range -0.47 to -0.27, sign flips 0; without severely affected donors -0.36 (p 0.148, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for CHRM1 in dopamine neurons.

case closed: nothing better to follow up.

receipt 0035: CHRM1 in dopamine neurons, resilience

power
full sample -0.24 (p 0.230, n 55), 95% CI -0.47 to +0.03. the interval is wide: not enough donors to tell.
confounder
adjusted for age, sex and PMI: -0.26 (p 0.185, 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 0.178, n 55). could be the mix.
skeptic
leave-one-out range -0.29 to -0.18, sign flips 0; without severely affected donors -0.25 (p 0.212, n 46). fragile.
cell type
no other cell group does better.
axis
no measure beats "differs in resilient donors (Lewy pathology, no parkinsonism)" for CHRM1 in dopamine neurons.

case closed: nothing better to follow up.

receipt 0034: CHRM1 in dopamine neurons, braak

power
full sample -0.01 (p 0.897, n 84), 95% CI -0.23 to +0.20. the interval sits on zero: probably nothing there.
confounder
adjusted for age, sex and PMI: -0.09 (p 0.402, n 84). does not hold up.
composition
dopamine neurons share of nuclei vs axis -0.72 (p 1.8e-14); controlling for it: -0.09 (p 0.439, n 84). could be the mix.
skeptic
leave-one-out range -0.04 to +0.02, sign flips 14; without severely affected donors +0.00 (p 0.992, n 75). fragile.
cell type
strongest in OPCs: -0.31 (p 0.0043, n 84) vs -0.01 in dopamine neurons. proposing OPCs.
axis
no measure beats "tracks Braak Lewy-body stage" for CHRM1 in dopamine neurons.

follow-up registered; not confirmed in ventral tegmental area.
