The early numbers I read out of NY was 80% mortality rate for those put on ventilators. That type of number demands something other than randomized trials, you make a running total and go with the current best treatment you have working based on current knowledge, adjust as new numbers come out. That saves the most current lives at risk, which should be the ultimate goal. Randomized trials with find ultimate best treatment for future patients, but what about the 2000 people that died in the US yesterday. Did they get the best possible treatment with the current data on-hand? I doubt it.
