Data displayed in each cell are as follows: mean ± standard deviation were calculated using data on amount of time the activPAL was worn during waking hoursa and working hoursb
Mean difference between groups is calculated as EG-PG (95% CI = 95% confidence intervals of the difference between group means), and effect sizes are calculated using Cohen’s d
