  1. ↑ indicates an increase of 15 min in the activity duration
  2. ↓ indicates a decrease of 15 min. Adjustments were made for covariates such as age, gender, and urban–rural differences in the model
  3. * indicates P < 0.05. The zBFP regression coefficient indicates that when controlling for covariates, the change in zBFP due to equal time substitution of activity components is β*100%
