2 Fig 1 Cluster proportions for dichotomous variables used in K-means cluster analysis. The variables are ordered by between-cluster variations (from high to low variation). Abbreviation: COPD, chronic obstructive pulmonary disease.

3 Fig 2 The colors in this heat map represent quantiles. Black boxes indicate the cluster is on the low end of the distribution for the particular variable. White boxes indicate that the cluster is on the high end of the distribution for the particular variable. Clusters are ordered in similarity to each other. Variables are ordered in similarity to each other, in terms of their distribution over the 7 clusters. Abbreviation: COPD, chronic obstructive pulmonary disease.
