Multimorbidity and health-related quality of life (HRQoL) in a nationally representative population sample: implications of count versus cluster method for defining multimorbidity on HRQoL

Table 3 Prevalence of common clusters using count method and hierarchical cluster, weighted (N = 8,820)

	Components	n	Prevalence (%)	Jack-knife standard error	Methods
MM2+	any 2 (+) of 8 chronic conditions^a	2539	26.0	0.6	Count method
MM3+	any 3 (+) of 8 chronic conditions^b	1042	10.1	0.5	Count method
Cluster 1	CVD/Arthritis	934	9.1	0.5	Hierarchical cluster
Cluster 2	MDD/Anxiety Disorder	399	4.3	0.3	Hierarchical cluster

CVD Heart or circulatory condition, MDD Major depression disorder, MM multimorbidity. Sample size (n) are showed based on the raw data, proportion (%) are estimated with standard error based on the weighting strategy
^aMM2+ which means having any 2 or more chronic conditions out of asthma, cancer, stroke, CVD, gout rheumatism or arthritis and diabetes or high sugar levels, MDD and anxiety disorder
^bMM3+ which means having any 3 or more chronic conditions out of asthma, cancer, stroke, CVD, gout rheumatism or arthritis and diabetes or high sugar levels, MDD and anxiety disorder
