About one half of the pacer studies have reported results . . . others remain with reports or partially reported:

The table reflects data extracted for several published reports involving patients who have deployed diaphragmatic pacing among their treatments for amyotrophic lateral sclerosis. The table is like Swiss Cheese . . . many datums are missing because various authors specified some but not all the results.

These journal papers give thorough Amyotrophic Lateral Sclerosis syndrome introduction and show the achievements of medical science over the recent last centuries. Several are easy reads. The one from Doctors Brown and Al-Chalabi is likely the most difficult as it articulates the frontier of genetics found bearing on the discovered disease processes.
