Bronchoalveolar lavage data at the end of a 5-h low tidal volume mechanical ventilation (MV) following either a lipopolysaccharide (LPS) or vehicle (saline) aspiration in wild type (WT) and interleukin-6 knock-out (IL-6KO) mice receiving either recombinant human interleukin-6 (rHuIL-6) or vehicle (saline). a Total cell count of BAL fluid (cell/μL). b TNFα concentration in the BAL fluid (pg/mL). c MIP-2 concentration in the BAL fluid (pg/mL). d IL-6 concentration in the BAL fluid (pg/mL). e Total protein concentration in the BAL fluid (μg/mL). The symbol * denotes Benjamini-Hochberg corrected p value < 0.05 of Mann–Whitney pairwise comparisons (following Kruskal Wallis test). Data are presented as box and whiskers plots. N = 6 to 8 animals per group
