Predicting Early Bulbar Decline in Amyotrophic Lateral Sclerosis: A Speech Subsystem Approach

Table 2

Fixed effects and values for the LME models of the four subsystems (respiratory, phonatory, articulatory, and resonatory).

LME model	Fixed effect
	Intercept	Subsystem predictor	Time effect
Respiratory	202.96	−0.14 PCresp1 − 1.7 PCresp2	−0.019 time	0.87
Phonatory	155.3	0.0072 PCphon1	−0.032 time	0.90
Articulatory	115.13	−0.079 PCart1 + 0.08 PCart2 + 0.2 PCart3	−0.036 time	0.89
Resonatory	158.8	−0.067 PCreso1 − 0.12 PCreso2	−0.028 time	0.86
