Swarm cases

receipt 0506: LRRK2 in dopamine neurons, braak

power
full sample +0.44 (p 0.070, n 18), 95% CI -0.04 to +0.75. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.41 (p 0.091, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.39 (p 0.114, n 18). could be the mix.
skeptic
leave-one-out range +0.35 to +0.64, sign flips 0; without severely affected donors +0.44 (p 0.070, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for LRRK2 in dopamine neurons.

case closed: nothing better to follow up.

receipt 0003: LRRK2 in dopamine neurons, resilience

power
full sample -0.12 (p 0.556, n 55), 95% CI -0.37 to +0.15. 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: -0.11 (p 0.570, n 55). could be the mix.
skeptic
leave-one-out range -0.22 to -0.04, sign flips 0; without severely affected donors -0.14 (p 0.495, n 46). fragile.
cell type
no other cell group does better.
axis
no measure beats "differs in resilient donors (Lewy pathology, no parkinsonism)" for LRRK2 in dopamine neurons.

case closed: nothing better to follow up.

receipt 0002: LRRK2 in dopamine neurons, braak

power
full sample +0.00 (p 0.999, n 84), 95% CI -0.21 to +0.21. the interval sits on zero: probably nothing there.
confounder
adjusted for age, sex and PMI: +0.02 (p 0.882, n 84). does not hold up.
composition
dopamine neurons share of nuclei vs axis -0.72 (p 1.8e-14); controlling for it: +0.02 (p 0.882, n 84). could be the mix.
skeptic
leave-one-out range -0.02 to +0.03, sign flips 47; without severely affected donors +0.07 (p 0.543, n 75). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for LRRK2 in dopamine neurons.

case closed: nothing better to follow up.
