However, VC measures are challenging to perform among pALS, especially bulbar pALS.

Venous bicarbonate negatively correlated with ALSFRS-R (<i>ρ</i> = −0.377, <i>p</i> < 0.001), specifically among bulbar pALS (<i>ρ</i> = −0.595, <i>p</i> < 0.001), but positively correlated with KING's stage (<i>ρ</i> = 0.248, <i>p</i> = 0.007).
