Population numbers for the year 2009 were used to calculate Q fever incidence for Q fever-affected areas.
Additionally SMRs were calculated for rheumatic fever and chronic rheumatic heart disease (ICD-9: 390–398/I00 I09 I00 I09).
The only clinical significant difference between patients with non-complicated sepsis and septic shock were: (1) age, (2) presence of bloodstream infection, (3) sepsis severity score SOFA calculated 48 hours after fever onset, and (4) MASCC at the time of neutropenic fever.
We utilized the SOFA score calculated 48 hours after fever because it segregates each outcome group better than SOFA at the time of fever onset (Table 1).
Similarly, the lowest dose group had the fewest fever hours, calculated as the sum of significant temperature elevations, and the highest dose group had the most.
The duration of fever was calculated as the number of days with elevated body temperature (≥ 40.0°C) [ 14].
The magnitude of fever was calculated as the area under the temperature curve for each lamb as described by [ 21].
Because of the passive nature of the surveillance and the requirement for fever, our calculated incidence may underestimate the true incidence of ILI in the cohort.
Salmonella enterica serotype Typhi (S. typhi), the causative agent of typhoid fever, was calculated to have caused approximately 200,000 deaths globally in 2000 [ 1].
Standard diagnostic accuracy indices of sensitivity, specificity with exact 95% confidence intervals (CIs) and interquartile ranges (IQRs) of days of fever were calculated by using Stata/SE 8.0 (Stata Corp., College Station, TX).
