The data comes from a Richardson et-al paper and is comparing apples to apples:

Quote:
Mortality rates for those who received mechanical ventilation in the 18-to-65 and older-than-65 age groups were 76.4% and 97.2%, respectively
The numbers cited in Patterson paper refer to patients that where in ventilators. The 10 were critical: "patients had significant pre-existing comorbidities and were receiving intensive care treatment including mechanical ventilation or supplemental oxygen for ARDS".
Therefore, I believe that the comparison is correct. Some papers in China mention 98% whereas some in the U.K. mention 65%. The problem is, the condition of the patients varies substancialy (the definition of severe/critical), however Patterson paper refers to Montefiori (in N.Y.) same as the Richardson paper (patients in N.Y. area). So is a good comparison imo.
