¹Baseline information for the sub analysis of IL28 12979860. Two hundred and fifty-two patients are reported to be enrolled, however adding the genotypes yields 253 patients. Likevise biopsies from 228 patients are described, however when adding the Ishak scores only yields 216 patients;

²Biopsies only available for 142 patients;

³Histology available for 44 patients;

⁴Lagging et al provided baseline demographics in accordance with IL-28 genotype (only baseline characteristics for rs12979860 are reported in the review, as these were representative for the study population). A box stretching over two - or more genotypes or fibrosis stage, indicates that the number refers to the combined group.
