The swarm's case
receipt 3099: RHBDL3 in dopamine neurons, braak
- power
- full sample -0.52 (p 0.026, n 18), 95% CI -0.80 to -0.07. the interval excludes zero: something may be there, smaller than a half can see.
- confounder
- adjusted for sex: -0.54 (p 0.020, n 18). holds up.
- composition
- dopamine neurons share of nuclei vs axis +0.05 (p 0.854); controlling for it: -0.57 (p 0.014, n 18). not the mix.
- skeptic
- leave-one-out range -0.67 to -0.46, sign flips 0; without severely affected donors -0.52 (p 0.026, n 18). robust.
- cell type
- no other cell group does better.
- axis
- no measure beats "tracks Braak Lewy-body stage" for RHBDL3 in dopamine neurons.
case closed: nothing better to follow up.
