Figure 2. Association between hourly physical activity (in SD units) and cardiovascular disease, cardiovascular mortality, and all-cause mortality. (A) The risk on incident cardiovascular disease; (B) The risk of cardiovascular mortality; (C) The risk on all-cause mortality. Multivariate Cox proportional hazard regression model was adjusted for age, sex, ethnicity, qualification, household income, smoking status, alcohol consumption, BMI, sleep chronotype, and glycated hemoglobin A1c at baseline. Results should be interpreted with caution due to multiple comparisons. These analyses are exploratory and should not be interpreted as causal. HR: Hazard ratio; BMI: body mass index.
