Procalcitonin Clearance for Early Prediction of Survival in Critically Ill Patients with Severe Sepsis

Table 3

PCT clearance in survivors and nonsurvivors.

	Sepsis cohort; (𝑛=67)	Survivors; (𝑛=40)	Nonsurvivors; (𝑛=27)	𝑃
		𝑛=39	𝑛=24
PCTc-24	8.7 (−90.3–45.8)	24.7 (−48.2–45.0)	−60.3 (−423.2–54.6)	0.10
		𝑛=35	𝑛=20
PCTc-48	31.6 (−67.1–68.7)	45.8 (−4.5–70.2)	−54.5 (−369.0–53.7)	0.02

Data are presented as median (interquartile range). The minus sign indicates that the PCT level increased relative to the baseline PCT. Comparisons of the levels between survivors and nonsurvivors were analysed with Mann-Whitney test.
