Fig. 2: Decomposition of changes in prevalent metabolic syndrome cases by sex, 2000–2023.
From: Worldwide trends in metabolic syndrome from 2000 to 2023: a systematic review and modelling analysis

Stacked decomposition of net change in prevalent metabolic syndrome cases (absolute counts) between 2000 and 2023 for women (left) and men (right). Bars show the reference number of cases in 2000 and the total cases in 2023; intermediate segments decompose the net change into the population effect (change due to population growth/age structure), prevalence effect (change due to shifts in age-specific prevalence), and interaction effect (joint effect of population and prevalence changes). Y axis: number of prevalent cases; X axis: year (2000 baseline and subsequent years shown).
