3. RESULTS
A total of 173 patients with a mean age of 47.6 ± 16.4 years were included in the study. Of the patients, 57.8% (n=100) were male and 49.2% (n=73) were female. The demographic and clinical characteristics of the patients are given in Table 1. The source of infection was detected in the thoracic and abdominal CT scans of 31.2% (n=54) of the patients. Gender, diastolic blood pressure, respiratory rate, and body temperature did not statistically significantly differ between the patients with and without an infection source detected on CT. There was also no significant difference between these two groups in relation to the white blood cell (WBC) and C-reactive protein (CRP) levels (Table 2). Of the patients, 41% (n=71) had one or more comorbidities. In the single logistic regression analysis, age, systolic blood pressure, heart rate, procalcitonin (PCT), and presence of comorbidity were evaluated as risk factors for the presence of infection in the thoracic and abdominal CT scans. According to the multiple logistic regression analysis, age ≥ 65 years [odds ratio (OR):2.72, 95% confidence interval (CI):1.15-4.35, p<0.001), presence of comorbidity (OR:2.37, 95% CI:1.08-4.14, p=0.033), and PCT positivity (OR:2.54, 95% CI:1.29-4.95, p=0.006) were determined as risk factors for the presence of infection in CT (Table 3).
