Table 1 Summary statistics of the demographic features, vital signs, and COPD characteristics of the study sample. CAT: COPD assessment test, COPD: chronic obstructive pulmonary disease, ER: emergency room/ department, FEV1: the vital capacity that a person can expire in the first second of forced expiration, SaO2: blood oxygen saturation, YoA: years of age.
