But now you have to add back in the number of deaths that still need to be counted because the final few patients still alive haven't reached the 28 day observation window yet. This is a complete guess but let's say since the Jan. 6 CC there are about 40 left still within 28 days. I picked 40 patients because there was such an accelerated enrollment in the final few days. If we assign a 23% mortality to that group: 40x.23=9. So you subtract 9 but add 9 means its a wash.
