Associations between daily average pollutant measurement; and baseline to follow-up changes in endothelial function, systolic blood pressure and diastolic blood pressure, in single-pollutant (circle) and two-pollutant (triangle) models. RHI reactive hyperemia index. Multivariable models with random subject intercepts, adjusted for continuous temperature (degrees Celsius), alcohol intake (yes/no) and caffeine intake (yes/no) in the last 24 h. β-coefficients represent the change per IQR increase in exposure in a single-pollutant model (filled circle) or a two-pollutant (filed triangle) model (i.e. air pollutant + noise). β-coefficients for noise are shown in the following order: noise estimate in a single-pollutant model, followed by the noise estimate in two-pollutant models with UFPs and BC, respectively. Refer to Supplementary Table S3 (single-pollutant models) and S5 (two-pollutant models).
