Sex: F: female; M: male; risk class after Fine et al. [32]. “temperature” is the highest measured temperature within the first three days outlined. First day sub-febrile temperature: the first day the patient shows temperatures below 38.0°C. Leucocytes: highest number of leucocytes within the first three days. Lc. end: the count of leucocytes at discharge of the hospital. In case of normal leucocytes, no further recording was performed. CRP 1st and 3rd days: highest value within the first three days as in-patients. CRP days 4 till 9: the lowest value within this time span. CRP end: CRP at end of treatment. †: Death.
