Swarm cases

receipt 0536: COMT in dopamine neurons, braak

power
full sample -0.06 (p 0.807, n 18), 95% CI -0.51 to +0.42. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.13 (p 0.621, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.09 (p 0.715, n 18). could be the mix.
skeptic
leave-one-out range -0.19 to +0.08, sign flips 1; without severely affected donors -0.06 (p 0.807, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for COMT in dopamine neurons.

case closed: nothing better to follow up.

receipt 0048: COMT in dopamine neurons, resilience

power
full sample -0.09 (p 0.659, n 55), 95% CI -0.34 to +0.18. the interval is wide: not enough donors to tell.
confounder
adjusted for age, sex and PMI: -0.11 (p 0.570, 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 0.599, n 55). could be the mix.
skeptic
leave-one-out range -0.17 to +0.00, sign flips 2; without severely affected donors -0.08 (p 0.690, n 46). fragile.
cell type
no other cell group does better.
axis
no measure beats "differs in resilient donors (Lewy pathology, no parkinsonism)" for COMT in dopamine neurons.

case closed: nothing better to follow up.

receipt 0047: COMT in dopamine neurons, braak

power
full sample +0.11 (p 0.331, n 84), 95% CI -0.11 to +0.31. the interval sits on zero: probably nothing there.
confounder
adjusted for age, sex and PMI: +0.11 (p 0.310, 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 0.931, n 84). could be the mix.
skeptic
leave-one-out range +0.08 to +0.14, sign flips 0; without severely affected donors +0.12 (p 0.299, n 75). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for COMT in dopamine neurons.

case closed: nothing better to follow up.
