Optimizing hepatitis C therapy in HIV/hepatitis C virus (HCV) coinfected patients: Analysis of HCV viral kinetics on treatment.
Article in The Canadian journal of infectious diseases & medical microbiology = Journal canadien des maladies infectieuses et de la microbiologie medicale, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionHepatitis C virus (HCV) infection is potentially curable, but the sustained virological response (SVR) has been shown to be lower in patients coinfected HIV. A single-centre experience treating individuals with HCV and HIV coinfection is reported.
methodsTwenty-one patients who received standard doses of pegylated interferon with weight-based dosing of ribavirin (mean 14.3 mg/kg) were retrospectively reviewed. Qualitative HCV polymerase chain reaction (PCR) was performed prospectively every four weeks if the patient remained HCV PCR positive. All patients with HCV genotype 1 were treated for 48 weeks. Patients with genotype 2 or 3 were treated for 24 weeks and 32 weeks to 36 weeks if their HCV RNA level was undetectable after four weeks (RVR4) or eight weeks (RVR8) of therapy, respectively. If RVR8 was not achieved, the treatment was continued for 48 weeks.
resultsThere were no dropouts or dose reductions within the first 12 weeks of treatment. SVR status was available for 20 patients and adequate serum for viral kinetics analyses was available for 17 patients. Eighty per cent of the patients achieved SVR (50% genotype 1; 100% genotypes 2 and 3). The week 8 viral load remained elevated for all genotype 1 nonresponders. DISCUSSION: High effectiveness rates were seen, particularly in patients with HCV genotype 2 and 3 who were treated for shorter durations. HCV viral loads after eight weeks of therapy helped distinguish patients with HCV genotype 1 who would respond to therapy.
