研究者算錯了。JAMA 的審稿人也是吃幹飯的。美國人的數學：（， 已經更正了。 （見內）

......

Two days after releasing the study, the Journal (JAMA) issued a clarification, deleting the 88% figure from the abstract and saying that most ventilator patients in the study were still hospitalized and that the mortality rate is expected to come down as more results come in. The clarification also stated that 24.5% of the total number of patients who had received ventilator treatment had died, while 3.3% survived and were discharged. The rest, or 72.2%, remained hospitalized as of April 4.

所有跟帖： 

• 若按此比例，入院上呼吸機3.3%存活，24.5%死亡，存活/死亡=13.4%，就是說死亡比86.6%。 -pickshell- ♀ (602 bytes) () 05/09/2020 postreply 05:39:18

• 嗯，沒造假，真實的也挑不出毛病，可稍揉捏下能呈現多種不同結果。 -pickshell- ♀ (0 bytes) () 05/10/2020 postreply 07:54:28
