Swarm cases

receipt 9578: CNTN3 in dopamine neurons, braak

power
full sample +0.65 (p 0.0037, n 18), 95% CI +0.26 to +0.86. the interval excludes zero: something may be there, smaller than a half can see.
confounder
adjusted for sex: +0.65 (p 0.0037, n 18). holds up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.64 (p 0.0045, n 18). not the mix.
skeptic
leave-one-out range +0.59 to +0.75, sign flips 0; without severely affected donors +0.65 (p 0.0037, n 18). robust.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for CNTN3 in dopamine neurons.

case closed: nothing better to follow up.

receipt 9577: CNTN3 in oligodendrocytes, braak

power
full sample -0.04 (p 0.867, n 18), 95% CI -0.50 to +0.43. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.14 (p 0.579, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: -0.07 (p 0.781, n 18). could be the mix.
skeptic
leave-one-out range -0.14 to +0.09, sign flips 4; without severely affected donors -0.04 (p 0.867, n 18). fragile.
cell type
strongest in dopamine neurons: +0.65 (p 0.0037, n 18) vs -0.04 in oligodendrocytes. proposing dopamine neurons.
axis
no measure beats "tracks Braak Lewy-body stage" for CNTN3 in oligodendrocytes.
