  1. Data are presented as P-values for the interaction term and as β-coefficients (95% confidence intervals) for categorical variables and variables stratified using the median split.
  2. Adjusted for study, sex, ethnicity, age, device wear time, BMI, glucose, TAG, HDL, interaction term and aCRF, bsedentary time or cMVPA.
