ALS Patients Risk Time period

414 735,386 100% Did not take

033 058,218 100% Occasional

017 050,626 060% 15+ days per month, but less than ten years

005 020,283 044% 15+ days per month, ten years or more

056 093,227 110% unspecified

525 957,740 Totals

The following paper reflects the afore stated change in risk due to taking vitamin e for several periods of time . . . could the uptick for unspecified be due to people who are less concerned about their health? Note, the risk appears to be more than halved!

'new' risk chart

New Risk

the chart referenced above does much better job of presenting point of initial thread post; the chart shows the Vitamin E report indication Vitamin E may reduce ALS risk . . . in one situation, patients appeared to have risk of about 44% of normal.

What about familial cases . . . might Vitamin E reduce their risk too? If so, by how much? I take a stab at guessing familial cases have risk of developing amyotrophic lateral sclerosis circa 275 times the ordinary risk . . . I wonder if one at risk for familial amytrophic lateral sclerosis could never the less develop sporadic?
