Chance for “successful weaning” from a ventilator within 28 days in critically ill patients according to blood levels of lung injury biomarkers Surfactant Protein D and Gelsolin, adapted from Holm et al. [4]. Gelsolin categories are quartiles and “high-risk gelsolin” is the lowest quartile, “low-risk gelsolin” was the three remaining quartiles. “High-risk SPD” was the upper 15%-percentile, “low-risk SPD” were all other SPD measurements, according to Jensen et al. [1].
