Fig. 1: Prevalence of MetS in PD patients and control subjects in the years before the DoD.

The graph is a collection of points, each representing the prevalence in a specific year until the DoD (red dashed vertical line). The results are calculated on the basis of data collected in the previous year; for example, “−3” relates to the prevalence calculated during the fourth year (from year 3 to year 4) before the DoD. For controls, the DoD is defined by the DoD of their matched patient (see the Methods section). a Whole cohort. b Stratification by sex. Numbers in the figure indicate the annual count (averaged over 10 datasets) of PD patients and control subjects meeting the criteria for MetS before the DoD.
