Boxplots of three clusters across scores for depression, mobility, satisfaction with social roles and activities, and cognitive function. Clusters represent complex patient outcomes across multiple domains of health-related quality of life. Patients in cluster 1 had scores greater than 1 sd better than the U.S. population mean (50, horizontal line). Patients in cluster 2 had scores for satisfaction with social roles greater than 0.5 sd worse than U.S. mean with cognitive function, depression, and mobility scores near the U.S. mean. Patients in cluster 3 had scores greater than 1 sd worse than the U.S. population mean (high depression scores indicate more symptoms).
