Text: In the 110/233 analyzed patients (47. 2 %) with low initial procalcitonin (< 0. 25 g/L), suggesting the absence of systemic bacterial infection, those randomized to procalcitonin guidance (n = 50) had a significantly lower adverse outcome rate compared to controls (n = 60) : 4 % vs. 20 % (absolute difference -16. 0 %, 95 % confidence interval (CI) -28. 4 % to -3. 6 %, P = 0. 01), and significantly reduced antibiotic exposure [days] (mean 3. 7 4. 0 vs. 6. 5 4. 4, difference -2. 8 [95 % CI, -4. 4 to -1. 2], P < 0. 01).
