General linear model (analysis of covariance) between the subjects with >30% risk and CVD diagnosis. Standardised by age, sex and accelerometer wearing time.
*CVD risk is based on Framingham Risk Score (includes age, systolic blood pressure, total cholesterol, high-density lipoprotein cholesterol, smoking, diabetes and antihypertensive medication as explanatory variables).
†CVD diagnosis: ischaemic heart disease, acute myocardial infarction or combination of these.
‡The values denote: minutes (SD).
§The values denote: number of bouts (SD).
CVD, cardiovascular disease; MVPA, moderate-to-vigorous physical activity; SB, sedentary behaviour.
