Thing is, the numbers are something of an indictment in and of themselves With 35,000 people to treat, it would be TRIVIAL to randomize 10% and do a proper trial

This study could've paved the way for a successful treatment. Instead, we are now months into a pandemic, with billions spent on these patients, and still have no idea if what Mayo did was worthwhile or a waste of time

Worse, it's entirely possible that the treatment is harmful, but without an appropriate control group we can only hope that it isn't Very, very depressing

Also worth noting that for the main finding - i.e. people getting plasma early died less than those who got it late - THEY DIDN'T EVEN ADJUST FOR AGE AND SEX That's just...woeful. Maybe people who get plasma later are just older???

I mean, it's an observational study where they're comparing two groups, getting headlines across the world, but they haven't adjusted that estimate for ANYTHING including things that might make a huge difference

Have to say, the more I think about it the worse this study looks All these authors and no one thought to adjust for age? Or gender? Or one of the many biases that are likely to be present here?pic.twitter.com/z0UKMVKqTb
