I agree with all of this but you need to assign a factor. It's not 2 to 1 or 66 33 its 70 30. So you need to multiply the treatment arm by .42 for apples to apples comparison.
It’s my bet that when they unblind, they find that all the unmethylated survivors at or over 3 years were treatment patients. Should this turn out to be the case, that would represent a tremendous step forward for unmethylated patients, for whom nothing seems to work.
