Note. Vent, mechanically ventilated; Fac-Infect, arriving from a skilled nursing facility or chronic care hospital or a history of infection within the previous 6 months; CTD, connective tissue disease.
The percent resistance was only presented for cases with n > 10. Note that this is the modeled dataset, where the overall resistance was 46.8%.
