In most patients who received riluzole, therapy was initiated at the time of the first examination and diagnosis, prior to a documented 20 point progression. In contrast, NIV initiation and PEG placement were generally performed in patients who had reached an advanced degree of disability. Thus, the Cox model for disease progression did not include NIV and PEG use.
