Fig. 4From: Circulating fibrocytes traffic to the lung in murine acute lung injury and predict outcomes in human acute respiratory distress syndrome: a pilot studyCirculating fibrocyte concentration as predictors of mortality in subjects with ARDS. Kaplan-Meier survival analysis of subjects with ARDS, separated by peak circulating activated fibrocyte concentration threshold value of 4.8 × 106 cells/mL. Of the 42 subjects with ARDS, 9 subjects had values above and 33 subjects had values below the threshold. *, p = 0.028 at day 28 and **, p = 0.009 for the entire follow-up period by Log-rank testBack to article page
