Baseline characteristics overall and stratified by SMI.Abbreviations: SMI= skeletal muscle index; SD = standard deviation; BMI = body mass index; NRS 2002 = nutritional risk screening 2002; COPD = chronic obstructive pulmonary disease. We defined low SMI as the lowest quartile of SMI and high SMI as the other three quartiles of SMI of this study population.Association of SMI with clinical markers.Abbreviations: NRS denotes nutritional risk screening 2002; BMI denotes body mass index; ROC denotes receiver operator characteristic curve.Association of low SMI at level Th12 with clinical outcomes.Abbreviations: SD denotes standard deviation; OR denotes odds ratio; CI denotes confidence interval; AUC denotes area under the curve.Effects of nutritional support on clinical outcomes of patients in the lowest and in the other three quartiles of SMI at level T12.Abbreviations: OR denotes odds ratio; CI denotes confidence interval.
