The effect of NMB did not vary meaningfully according to ventilatory ratio (posterior probability of interaction, 62%) or baseline plasma levels of receptor for advanced glycation end-products, tumor necrosis factor receptor-1, IL-6, or IL-8 (posterior probabilities of interaction: 12%, 18%, 44%, and 22% respectively).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>These findings suggest that the mortality benefit of NMB varies with baseline Ers.
