From: The upper cervical spinal cord in ALS assessed by cross-sectional and longitudinal 3T MRI
Quantile function of baseline mean cervical spinal cord cross-sectional area in ALS and controls. (a) CSA in ALS was significantly smaller than in controls. (b) CSA was further significantly smaller in limb- compared to bulbar-onset ALS. *p ≤ 0.05, **p ≤ 0.001 (all statistical models are adjusted for baseline age).
