Comparison (Kruskal-Wallis) and correlation (Spearman) tests were used after performing normality tests. This study was approved by the Ethics Committee.Results: Table 1 summarizes the data for each GOLD stage. No significant difference was observed between stages I and II or I and III for any of the SGRQ domains. There were no significant correlations between FEV1 and the SGRQ scores.View this table:Table 1. Age, Sex, FEV1 and SGRQ escores according to GOLD stagesConclusion: The results suggest that there is no linearity between the severity levels of COPD and the SGRQ scores, including the activity and psychosocial impact domains. %U
