“…n c : number of cases; n p : number of participants; M: male; F: female; CHARIOT: collaborative group hepatitis C study using high-dose Pegasys RBV induction dose in genotype one; HPLC: high performance liquid chromatography; LC: liquid chromatography; MS: mass spectrometry; G1, 2, 3, 4: hepatitis C genotype 1, 2, 3, or 4 infection; NA: not available United States, and one (Kitson et al, 2013) in Australia. The five (Arteh et al, 2010;Amanzada et al, 2013;Kitson et al, 2013;Petta et al, 2013;White et al, 2013) studies assessed included a review of serum 25(OH) D status, and one (Lange et al, 2011) on 25(OH)D 3 and 1,25(OH) 2 D 3 status. Three studies (Amanzada et al, 2013;Kitson et al, 2013;Petta et al, 2013) included patients with chronic hepatitis C genotype 1 infection, one (Lange et al, 2011) with chronic hepatitis C genotype 1, 2, or 3-infection, one (White et al, 2013) with chronic hepatitis C genotype 1, 2, 3, or 4-infection, and one (Arteh et al, 2010) did not specify the kind of HCV type.…”
