Table 1.
Demographic and participant characteristics stratified by the NAFLD and significant fibrosis status.
The total number of participants (N) is non-survey weighted, while the means (SD) or the totals (%) for each variable are survey-weighted.
Table 2.
Estimated final model coefficient odds ratio (OR) for the NAFLD and significant fibrosis prediction models.
For each model, the variables are arranged in the order they entered the forward selection model with the corresponding cumulative CV-AUC due to adding each variable into the model. For example, in the NAFLD model, the row labeled Gender indicates that gender is the second variable that was added to the model and the corresponding AUC includes MVPA and Gender.

MVPA, LIPA and TLAC physical activity summaries by NAFLD (top panel) and significant fibrosis (bottom panel) status.
In panels A-F the Wilcoxon test showed a p-value < 0.001 indicating differences in physical activity between those who have NAFLD or fibrosis and those who do not have the disease.
