Data are presented as n (%) or median (interquartile range), unless otherwise stated. sCAP minor is the number of minor criteria for severe community-acquired pneumonia from the Infectious Diseases Society of America/American Thoracic Society 2007 community-acquired pneumonia guidelines 2007 and eCURB is the validated electronic version of CURB-65 (confusion, blood urea, respiratory rate, blood pressure, age 65 years) with weighted, continuous variables yielding a point estimate for 30-day mortality [13, 14]. PaO2: arterial oxygen tension; FiO2: fraction of inspired oxygen.
