Swarm cases

receipt 0563: GRIN3B in dopamine neurons, braak

power
full sample -0.60 (p 0.0086, n 18), 95% CI -0.83 to -0.18. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: -0.61 (p 0.0067, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.63 (p 0.0055, n 18). not the mix.
skeptic
leave-one-out range -0.70 to -0.55, sign flips 0; without severely affected donors -0.60 (p 0.0086, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for GRIN3B in dopamine neurons.

case closed: nothing better to follow up.

receipt 0092: GRIN3B in dopamine neurons, resilience

power
full sample -0.05 (p 0.817, n 55), 95% CI -0.31 to +0.22. the interval is wide: not enough donors to tell.
confounder
adjusted for age, sex and PMI: -0.03 (p 0.866, n 55). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.12 (p 0.542); controlling for it: -0.03 (p 0.883, n 55). could be the mix.
skeptic
leave-one-out range -0.15 to +0.05, sign flips 4; without severely affected donors -0.05 (p 0.807, n 46). fragile.
cell type
no other cell group does better.
axis
no measure beats "differs in resilient donors (Lewy pathology, no parkinsonism)" for GRIN3B in dopamine neurons.

case closed: nothing better to follow up.

receipt 0091: GRIN3B in dopamine neurons, braak

power
full sample +0.15 (p 0.180, n 84), 95% CI -0.07 to +0.35. the interval sits on zero: probably nothing there.
confounder
adjusted for age, sex and PMI: +0.13 (p 0.243, n 84). does not hold up.
composition
dopamine neurons share of nuclei vs axis -0.72 (p 1.8e-14); controlling for it: +0.12 (p 0.273, n 84). could be the mix.
skeptic
leave-one-out range +0.12 to +0.19, sign flips 0; without severely affected donors +0.17 (p 0.156, n 75). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for GRIN3B in dopamine neurons.

case closed: nothing better to follow up.
