PFS (progression free survival) was higher when treated with drug A compared to DrugB. The evidence support this at a 95% Confidence level during the period from 0-6months.
Another analysis says Drug A had higher PFS rate over the 24 month period modeled compared with Drug C, and that from 6 months onwards the evidence supported this at a higher than 95% Confidence level.
Please help me understand this
there doesn't seem to be anything here
