From: Regulation and prognostic relevance of serum ghrelin concentrations in critical illness and sepsis
Prognostic relevance of serum ghrelin in critically ill patients. (A) Kaplan-Meier survival curves of ICU patients with sepsis (n = 122) are displayed, showing that sepsis patients with high ghrelin levels (>20 pmol/L, black) have a decreased short-term mortality at the ICU as compared to patients with low ghrelin (≤20 pmol/L, grey). P-value from Cox regression analysis is given. (B) For the total cohort of all critically ill patients (sepsis and non-sepsis), ghrelin serum concentrations at admission to the ICU were significantly higher if no mechanical ventilation was required (P = 0.026). Box plot are displayed, where the 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 non-outlier values; asterixes and open circles indicate outlier values.
