Description of the six models and underlying rationale for the model
| Model number | Model name | Supplementary table | Description |
| 1 | Full model | Online supplemental table 2 | All the parameters studied are included (socio-demographic, biophysical and biochemical values) |
| 2 | Non-invasive model | Online supplemental table 3 | All the non-invasive parameters are included. This model can be used in any community health set-up with minimal equipment |
| 3 | Budget model | Online supplemental table 4 | In addition to the non-invasive model, this model includes low-cost biochemical parameters. |
| 4 | Model without liver enzymes | Online supplemental table 5 | The highest number of missing values in this study is from AST, ALT and GGT. This model was created to avoid the effects of the above missing values. This model includes all parameters in the full model except AST, ALT and GGT |
| 5 | Model with non-invasive parameters and liver enzymes | Online supplemental table 6 | This model was created to determine the effect of liver enzymes together with non-invasive parameters |
| 6 | Model with anthropometric parameters and lipid profile | Online supplemental table 7 | This model was created to determine the effect of lipid profile together with non-invasive parameters |
ALT, alanine aminotransferase; AST, aspartate aminotransferase; GGT, gamma-glutamyl transferase.
