  1. COPD: Chronic obstructive pulmonary disease; CABG: Coronary artery bypass grafting. GCS: Glasgow coma scale. ICU: Intensive care unit. Continuous normal data are represented as mean ± standard deviation. Continuous non normal data and ordinal data are represented as median (1st quartile – 3rd Quartile); Categorical data are represented as frequencies (Percentage). P'sds is the adjusted P value derived from the Holm-Sidak step-down procedure to correct for multiple comparisons.
