Please output the extracted information in JSON format. Do not output anything except for the extracted information. Do not add any clarifying information. Do not add any fields that are not in the schema. If the text contains attributes that do not appear in the schema, please ignore them.

Input:Peginterferon alfa-2a plus ribavirin for HIV-HCV genotype 1 coinfected patients: a randomized international trial.  The safety and efficacy of weight-based ribavirin (RBV) dosing regimens in patients with HIV-HCV coinfection has not been demonstrated in randomized clinical trials. This randomized, double-blind, international, parallel-group study in specialist outpatient clinics in the United States, Spain, and Portugal compares the efficacy and safety of 2 RBV dose regimens (800 mg/day and 1000/1200 mg/day) combined with peginterferon alfa-2a (40KD) in patients with HIV-HCV (genotype 1) coinfection. Patients with HIV-HCV coinfection, quantifiable HCV RNA in serum, HCV genotype-1 infection, compensated liver disease, and stable HIV disease (CD4+ count ≥100 cells/µL) with or without ongoing antiretroviral therapy were randomized to 48 weeks' treatment with RBV at standard dose (800 mg/day) or weight-based dose (1000 mg/day for patients weighing <75 kg; 1200 mg/day for patients weighing ≥75 kg) in combination with peginterferon alfa-2a (40KD) 180 µg once a week. Planned enrollment was 400 patients with ≥100 non-Latino African Americans. The primary endpoint was sustained virological response (SVR) (undetectable HCV RNA [<20 IU/mL] at the end of a 24-week untreated follow-up period [week 72]). SVR rates were 19% (26/135) and 22% (60/275) in patients randomized to RBV 800 mg/day and 1000/1200 mg/day, respectively (odds ratio, 1.15; 95% CI, 0.68-1.93; P = .6119). In the 1000/1200 mg/day RBV dose group, the incidence of hemoglobin reductions <100 g/L and anaemia reported as an adverse event were higher versus the standard 800 mg/day RBV dose group. Compared with the standard RBV dose (800 mg/day), weight-based RBV dosing (1000/1200 mg/day) did not significantly increase SVR rates, but did increase the incidence of anemia in HIV-HCV (genotype 1) coinfected patients.
