Swarm cases

receipt 11641: SMO in dopamine neurons, braak

power
full sample -0.28 (p 0.254, n 18), 95% CI -0.66 to +0.21. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.34 (p 0.173, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.45 (p 0.059, n 18). could be the mix.
skeptic
leave-one-out range -0.40 to -0.19, sign flips 0; without severely affected donors -0.28 (p 0.254, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for SMO in dopamine neurons.

case closed: nothing better to follow up.

receipt 11640: SMO in astrocytes, braak

power
full sample -0.45 (p 0.059, n 18), 95% CI -0.76 to +0.02. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.48 (p 0.044, n 18). holds up.
composition
astrocytes share of nuclei vs axis -0.21 (p 0.413); controlling for it: -0.41 (p 0.091, n 18). could be the mix.
skeptic
leave-one-out range -0.58 to -0.37, sign flips 0; without severely affected donors -0.45 (p 0.059, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for SMO in astrocytes.

case closed: nothing better to follow up.
