Swarm cases

receipt 3396: HAPLN2 in dopamine neurons, braak

power
full sample +0.08 (p 0.741, n 18), 95% CI -0.40 to +0.53. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: +0.09 (p 0.735, n 18). does not hold up.
composition
dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: +0.19 (p 0.455, n 18). could be the mix.
skeptic
leave-one-out range -0.02 to +0.21, sign flips 1; without severely affected donors +0.08 (p 0.741, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for HAPLN2 in dopamine neurons.

case closed: nothing better to follow up.

receipt 3395: HAPLN2 in oligodendrocytes, braak

power
full sample +0.01 (p 0.983, n 18), 95% CI -0.46 to +0.47. the interval is wide: not enough donors to tell.
confounder
adjusted for sex: -0.02 (p 0.949, n 18). does not hold up.
composition
oligodendrocytes share of nuclei vs axis +0.03 (p 0.915); controlling for it: +0.16 (p 0.521, n 18). could be the mix.
skeptic
leave-one-out range -0.11 to +0.13, sign flips 11; without severely affected donors +0.01 (p 0.983, n 18). fragile.
cell type
no other cell group does better.
axis
no measure beats "tracks Braak Lewy-body stage" for HAPLN2 in oligodendrocytes.
