re: Average versus Median
The reports regarding survival referenced in the table (whole thread is about the table) of studies rarely show survival rate more than three years for the set of patients . . . :
However:
The Lee (2013) study shows survival at 66.6 months (average) but the study includes 241 patients who were on the tracheostomy.
The Kollewe (2008) study shows 42.8 and I am currently reviewing same (. . . 42.8 is average rather than median).
quote from ALSA's web site taken on March 2, 2016
"Once ALS starts it almost always progresses, eventually taking away the ability to walk, dress, write, speak, swallow, and breathe and shortening the life span. How fast and in what order this occurs is very different from person to person. While the average survival time is 3 years, about twenty percent of people with ALS live five years, 10 percent will survive ten years and five percent will live 20 years or more."
