Swarm cases

receipt 0561: GRIN3A in dopamine neurons, braak

power
full sample +0.20 (p 0.434, n 18), 95% CI -0.30 to +0.61. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.18 (p 0.487, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.25 (p 0.315, n 18). could be the mix.
skeptic
leave-one-out range +0.07 to +0.36, sign flips 0; without severely affected donors +0.20 (p 0.434, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for GRIN3A in dopamine neurons.

case closed: nothing better to follow up.

receipt 0089: GRIN3A in dopamine neurons, resilience

power
full sample -0.10 (p 0.599, n 55), 95% CI -0.36 to +0.17. the interval is wide: not enough donors to tell.
confounder
adjusted for age, sex and PMI: -0.14 (p 0.474, n 55). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.12 (p 0.542); controlling for it: -0.14 (p 0.487, n 55). could be the mix.
skeptic
leave-one-out range -0.20 to -0.01, sign flips 0; without severely affected donors -0.17 (p 0.388, n 46). fragile.
cell type
no other cell group does better.
axis
no measure beats "differs in resilient donors (Lewy pathology, no parkinsonism)" for GRIN3A in dopamine neurons.

case closed: nothing better to follow up.

receipt 0088: GRIN3A in dopamine neurons, braak

power
full sample -0.05 (p 0.637, n 84), 95% CI -0.26 to +0.16. the interval sits on zero: probably nothing there.
confounder
adjusted for age, sex and PMI: -0.06 (p 0.597, 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 0.555, n 84). could be the mix.
skeptic
leave-one-out range -0.09 to -0.02, sign flips 0; without severely affected donors +0.00 (p 0.986, n 75). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for GRIN3A in dopamine neurons.

case closed: nothing better to follow up.
