* The DNFCS does not present data for the total group. Therefore, values are calculated using available subgroup data. Moreover, not all data is available in the DNFCS report, which is indicated by “-”. ** In the DNFCS only age ranges per subgroup are provided. ALT: Alanine aminotransferase; AST: Aspartate aminotransferase; GGT: Gamma-glutamyltransferase; GFR: Glomerular filtration rate.
