Abstract excerpt

PURPOSE: Cluster analysis has been proposed to examine phenotypic heterogeneity in chronic obstructive pulmonary disease (COPD). The aim of this study was to use cluster analysis to define COPD phenotypes and validate them by assessing their relationship with mortality. METHODS: Male subjects with COPD were recruited to identify and validate COPD phenotypes. Seven variables were assessed for their relevance to...
