Read the above quote carefully. They say "mortality rate 78% lower" in the first sentence. But the second sentence says "achieved maximum benefit of 82% less mortality". The 82% number does not come from all 62 critical patients. I just tried every permutation of 19 placebo and 43 leronlimab and none came out to 82%. So my guess is that the 82% number comes from a subgroup within the 62 patients. Maybe it is only ECMO patients that received the "maximum benefit" of 82% less mortality. Or maybe it is an age group that received the "maximum benefit" of 82%. And the 82% is probably 63%.
The 82% mortality benefit at 14 days is 100% a lie! They had bad data so they datamined and manipulated the results to the maximum benefit!
