Figure 7 Nordpred projections of osteoarthritis burden by sex in China. Trends for total incident cases (A), total prevalent cases (B), and total YLDs (C). The dotted line refers to the observed value (before 2019) and the solid line refers to the projected value (after 2019). The shading indicates whether the rate remained stable (baseline reference), decreased by 1% per year (lower limit), or increased by 1% per year (upper limit). YLDs – years living with disability, BAPC – Bayesian age-period-cohort. (Created by R software, version 4.2.1, R Foundation for Statistical Computing).
