Concentrations of hormones and cytokines in serum and alveolar lining fluid.

<p>Proteins are ranked from highest to lowest ALF / serum concentration, after adjustment for dilution during the lavage procedure. Data are median (Q1, Q3). P-value is for the difference between median concentrations in serum and median concentrations in ALF, from Wilcoxon′s signed-rank test. Proteins are sorted from the most to the least concentrated in ALF relative to serum.</p><p>Concentrations of hormones and cytokines in serum and alveolar lining fluid.</p
