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.
