Prevalence of tested pathogens in CoLaus|PsyCoLaus study in participants with and without coronary heart disease (CHD).

Overall serostatus for the 22 pathogens are shown in the CHD-positive group (individuals with at least one CHD event during follow-up) or CHD-negative group. The y-axis indicates the relative percentage within each group. Pathogens are ranked in ascending order of overall seropositivity (all individuals combined).

Hazard ratio (HR) and 95% confidence intervals of coronary heart disease (CHD) occurrence according to associated factors.

HR > 1 indicates an increased risk of CHD, whereas HR < 1 indicates a protective effect. p-Values (p) for each factor based on the multivariable Cox regression are shown.

Appendix 2—figure 1
Pairwise correlations between quantitative characteristics significantly associated with coronary heart disease (CHD) risk in the univariable Cox proportional hazard models.

Pearson’s correlation values are displayed, along with linear fits between variables.

Appendix 2—figure 2
Strength of association for each pair of categorical variables significantly associated with coronary heart disease (CHD) risk in univariable Cox proportional hazard models.

Cramer’s V values are displayed.

Appendix 2—figure 3
Graphical test of proportional hazards assumption (Schoenfeld test).

The graphs show the scaled Schoenfeld residuals over time. The p-values (p) of the variables and the model as a whole were shown in the plot. A significant p-value (< 0.05) indicates that the variable violates the proportional hazard assumption. The solid line represents the smoothing fitted spline, and the dashed lines the confidence bands at two standard errors. Global Schoenfeld test p=0.58.

Appendix 2—figure 4
Distribution of individuals according to their exposure to infectious agents (pathogen burden).

Bar plot showing the number of participants for each cumulative number of positive serological results, reflecting simultaneous ongoing chronic/latent infections. Sample sizes for each group are shown above the box.
