To me it appears that your 2 charts do not jive:
In June you show 100 alive, of which 85 in Treatment column and remaining 15 in Control column.
And ... some time later ... after 2 additional deaths, there are now 98 Alive, of which 88 in Treatment column and remaining 10 in Control column.
If your June numbers were correct and there were 85 alive, how can there be 3 additional people alive (suddenly there are 88 alive in this category?) weeks/months later after an additional 2 deaths?
