Disease prevalence networks among females with multimorbidity, by age group, in BC, Canada (2001/02–2020/21). Age- and sex-stratified disease prevalence networks for females. Diseases are represented as nodes, and temporal relationships between co-occurring diseases are represented as links. Node size indicates single disease prevalence. Link thickness and color indicates the combined (co-occurring) prevalence of the linked disease pair, and link arrows represent the directionality of disease relationships (first disease–second disease). Network density is a ratio of the number of observed network links over the total possible links. Descriptive information for prevalence networks is presented in the right-hand panel. The top bar plot presents the top 10 most prevalent links in each age-stratified network. The bottom plots present node degree (the number of links coming into or out from each node) and node strength (sum of link weights for links coming into or out from each node)
