'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?
