Just to back up your statement, from the actual study, under Limitations:

> Fifth, clinical outcome data were available for only 46.2% of admitted patients. The absence of data on patients who remained hospitalized at the final study date may have biased the findings, including the high mortality rate of patients who received mechanical ventilation older than age 65 years.

MedPageToday notes this, but unlike the study, they start with the headline of 90% mortality, and don't mention until the very last sentence "that clinical outcome data were only available for less than half of admitted patients." This just seems wildly irresponsible reporting; I don't know if the reporter didn't really understand the limitations, or what, but at the very least, that should not have been the headline, not without a major proviso included at the very beginning.
