Clinical Sema7A values correlate with leukocyte count and clinical oxygenation values in patients with ARDS. Demographic data and samples of patients undergoing elective surgery with postoperative ventilation and ICU stays and patients admitted to the ICU for ARDS with severe pulmonary inflammation who were matched with propensity score. (A) Demographic data, ICU scores, and laboratory values for both patient groups are presented as means ± standard deviations, with values compared using the Wilcoxon rank-sum test. Significant values are set in bold. (B) The correlation of various laboratory values, ventilation parameters, and oxygenation values with serum levels of Sema7A is depicted. Pearson r and the lower and upper limits of the 95% confidence interval are shown. Significant correlations are highlighted in red. BE, Base excess; ICU, intensive care unit; INR, International Normalized Ratio; LDH, Lactate dehydrogenase.
