Use of factor analysis to consolidate multiple outcome measures in chronic obstructive pulmonary disease.
Each patient had measurements made of 28 variables, including multiple parameters of pulmonary function, exercice tolerance and gas exchange.
Factor analysis using a maximum likelihood iterative solution was performed.
The factors were then rotated to a varimax solution.
The analysis yielded four meaningful factors: exercise tolerance, disease severity, lung volumes and flow rates.
Exercise tolerance and disease severity were the most important factors accounting, respectively, for 44 and 13% of the common variance.
