nyboy1960 wrote that he read that only a 1/3 of MS patients respond to A-B-C
drugs. I don't think this is right; do you have a source? There has been a lot
of confusion around this. The clinical trials showed that all these drugs
reduced exacerbations by about 1/3. Some people misunderstood this to mean that
1/3 of all patients had no exacerbations and the others were unaffected.
