All coefficients for LPA represent a unit change in outcome per 120 min change in activity.

All coefficients for MVPA represent a unit change in outcome per 10 min change in activity.

All models were adjusted for age, BMI, smoking status, fitness, the resting value of the outcome of interest and the opposing activity variable (LPA or MVPA).

*Presented as least squared means (SE).

†P values indicate the probability of the associated beta-coefficient being equal to 0.

‡The magnitude of effect (f

^{2}) is calculated for the interaction term and can be interpreted as small: f^{2}≥0.02, medium: f^{2}≥0.15 and large: f^{2}≥0.35.BMI, body mass index; BP, blood pressure; β (SE), beta coefficient (SE).
