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

Figure 2

Scatter plots of the relation between speaking rate and each subsystem predictor accounting for time and subject effects: (a) respiratory, (b) phonatory, (c) articulatory, and (d) resonatory. On the -axis is the subsystem predictor adjusted for time, which is the combination of each subsystem predictor and the effect of time on speaking rate. On the -axis is the normalized speaking rate derived by subtracting the subject-dependent random effect from speaking rate. The lines are the linear fits based on the LME models.
