Extended data
Extended Data Fig. 1 Flowchart of inclusions and exclusions.
A total of 502,536 individuals were enrolled in the UK Biobank. Participants were excluded if they had pre-existing cardiometabolic diseases (type 2 diabetes, coronary artery disease, stroke, or heart failure) or depression at baseline. A final analytical sample of 467,592 participants was included in the study.
Extended Data Fig. 2 Comparison of transition probabilities from healthy or disease states to cardiometabolic diseases and depression (n=467,592).
(A) Transition probabilities from healthy states to CMDs (Baseline-CMDs) compared to transition probabilities from depression to CMDs (DEP-CMDs) at 5, 10, and 15 years. (B) Transition probabilities from healthy states to depression (Baseline-DEP) compared to transition probabilities from CMDs to depression (CMDs-DEP) at 5, 10, and 15 years. (C)Transition probabilities from healthy states to CAD (Baseline-CAD) compared to transition probabilities from depression to CAD (DEP-CAD) at 5, 10, and 15 years. The transition probabilities were calculated using multistate models adjusted for age, sex, ethnicity, Townsend deprivation index, employment status, education level, smoking status, drinking status, physical activity, diet quality score, sleep duration, body mass index, and family history of type 2 diabetes, cardiovascular disease, and depression. Data are presented as estimated transition probabilities (center) with 95% confidence intervals (error bars). P values are two-sided and were calculated using t-tests. Abbreviations: CAD, coronary artery disease; CMDs, cardiometabolic diseases; DEP, depression.
Extended Data Fig. 3 Mean coefficients of multiomic predictors across nine transition prediction models.
Mean coefficients of polygenic risk scores (A), top 20 selected metabolites (B), top 20 selected proteins (C), and 45 multiomic predictors (D) across the nine transitions.
Extended Data Fig. 4 Associations and shared patterns of clinical makers.
(A) Volcano plots of markers with the nine transitions. The associations were estimated based on multistate models adjusted for age, sex, ethnicity, Townsend index, employment status, education level, smoking status, drinking status, physical activity, diet quality scores, sleep duration, body mass index, and family history of type 2 diabetes, cardiovascular disease, and depression. The top five most positive and top five most negative metabolites and proteins for nine transitions are labeled with the abbreviations, and their full names are provided in Supplementary Table S18. P values were two-sided and adjusted for multiple comparisons using the Benjamini-Hochberg false discovery rate (FDR) correction, performed independently for each omics dataset. The dashed line indicates FDR-adjusted P = 0.05. (B) The number of shared and distinct markers for the nine transitions. (C) Frequent markers identified across nine outcomes.
Extended Data Fig. 5 Sensitivity analysis of transition patterns and probabilities.
(A) Complete-case analysis of transition probabilities in the UK Biobank at 5, 10, and 15 years (n=417,275). (B) Transition patterns in the HRS external validation cohort (n=8623). (C) Transition probabilities in the HRS cohort at 8 years. The transition probabilities were calculated using multistate models adjusted for age, sex, ethnicity, Townsend deprivation index, employment status, education level, smoking status, drinking status, physical activity, diet quality score, sleep duration, body mass index, and family history of type 2 diabetes, cardiovascular disease, and depression. Data are presented as estimated transition probabilities (center) with 95% confidence intervals (error bars). P values are two-sided and were calculated using t-tests. Abbreviations: CMDs, cardiometabolic diseases; DEP, depression.
Extended Data Fig. 6 Complete-case analysis of metabolomics and proteomics signatures in UK Biobank (n=417,275).
(A) Volcano plots of all metabolites with the nine transitions. (B) Volcano plots of all proteins with the nine transitions. The associations were estimated based on multistate models adjusted for age, sex, ethnicity, Townsend index, employment status, education level, smoking status, drinking status, physical activity, diet quality scores, sleep duration, body mass index, and family history of type 2 diabetes, cardiovascular disease, and depression. The top five most positive and top five most negative metabolites and proteins for nine transitions are labeled with the abbreviations, and their full names are provided in Supplementary Table S18. P values were two-sided and adjusted for multiple comparisons using the Benjamini-Hochberg false discovery rate (FDR) correction, performed independently for each omics dataset. The dashed line indicates FDR-adjusted P = 0.05. Abbreviations: CMDs, cardiometabolic diseases; DEP, depression.
