1. Respiratory sarcopenia is associated with postoperative pulmonary complications in humans (adjusted mean odds ratio: 2.79; 95% credible interval: 0.75-7.37; unadjusted 55% vs. 27%).

   “Bayesian logistic regression adjusting for age, smoking, and nutritional status showed that respiratory sarcopenia was strongly associated with PPCs (adjusted mean odds ratio: 2.79; 95% credible interval: 0.75-7.37)”
