Description of intervention(s) / exposure
This study measured the quality of life and the BODE index.
Quality of life was assessed by questionnaire St George's Respiratory Questionnaire (SGRQ). This questionnaire has a scale ranging from 0 to 100%, and the higher the score, the higher the quality of life of the patient. The BODE index was calculated according to the body mass index (BMI), forced expiratory volume in the first second (FEV1) post-bronchodilator, the 6-minute walk test (6MWD) and degree of dyspnea. The BODE index has a scale of 0 to 10 points, and the closer to ten, the worse the prognosis.
The correlation between the quality of life and the BODE index was assessed using Pearson correlation.
The study lasted 4 years.
