Progressive decline in averaged SICI recorded from the APB of patients with limb and bulbar onset ALS. Line plots depict the overall ALS cohort (solid line), limb-onset subgroup (dotted line), and bulbar-onset subgroup (dashed line) over four assessment timepoints: Initial, < 6 months, > 6 months, and > 12 months. Error bars represent 95% confidence intervals.
