a Cluster Descriptions by Less Severe Disease Features. b Cluster Descriptions by More Severe Disease Features. The first column describes the cluster number, and the second column describes the cluster name. The third column includes significant differences in the six most important variables for clustering; arrows indicate a significant difference between less severe clusters (1, 2, 3) and more severe clusters (4, 5, 6) (q < 0.05). The fourth column shows which severe disease features are present in clusters; shading in the Venn diagram indicates that the majority of individuals had that particular disease feature; partial shading indicates half of individuals had the disease feature. The fifth column describes significant pairwise differences between clusters (q < 0.05). Finally, the sixth column describes the mean Wasfi score for that cluster
