Figure 2. Procalcitonin levels between survivors and non-survivors during shock and infection phases. (a): shock phase; (b) infection phase. Mann-Whitney U test. Data are expressed as median (interquartile range). PCT: procalcitonin; PCT-SP: The maximum concentration of PCT during the shock phase after burn injury; PCT-IP: The maximum concentration of PCT during the infection phase after burn injury.
