Figure 5From: Circulating retinol binding protein 4 in critically ill patients before specific treatment: prognostic impact and correlation with organ function, metabolism and inflammationPrognostic relevance of serum RBP4 in critically ill patients. (a) Patients who die during the course of ICU treatment have significantly (P = 0.004) lower serum RBP4 levels on admittance to ICU than survivors. Boxplots are displayed, where the black bold line indicates the median per group, the box represents 50% of the values, and horizontal lines show minimum and maximum values of the calculated nonoutlier values; asterisks and open circles indicate outlier values. (b) Kaplan-Meier survival curves of ICU patients (n = 123) are displayed, showing that patients with high RBP4 levels (> 12 mg/L, black) have a decreased short-term mortality at ICU as compared to patients with low RBP4 (< 12 mg/L, gray). P value from Cox regression analysis is given. (c) Kaplan-Meier survival curves of ICU patients show no difference with respect to the long-term survival between patients with RBP4 levels (> 12 mg/L, black) and patients with low RBP4 (< 12 mg/L, gray). n.s., not significant.Back to article page
