Early View of the Effectiveness of New Direct-Acting Antiviral (DAA) Regimens in Patients with Hepatitis C Virus (HCV).
Article in Advances in therapy, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers.
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
introductionClinical trials have demonstrated the efficacy of all-oral direct-acting antiviral (DAA) regimens in the treatment of patients infected with hepatitis C virus (HCV). This study assessed real-world effectiveness of two recently approved regimens; paritaprevir/ritonavir/ombitasvir; dasabuvir (3D), and sofosbuvir/ledipasvir (SOF/LDV) in patients with HCV genotype 1.
methodsA retrospective analysis of administrative claims data (IMS Health Patient-Centric Data Warehouse/Medivo database) from October 1, 2013 to August 14, 2015 was conducted. Patients ≥19 years of age with a HCV genotype 1 infection, a prescription fill for 3D or SOF/LDV, and ≥1 HCV viral load (VL) assessment from weeks 4-30 post-treatment were selected for analysis. Percentages of patients achieving sustained virologic response (SVR; defined as HCV RNA ≤43 IU/mL) were determined. Unadjusted SVR rates were compared between treatment groups using Fisher's exact tests. SVR rates were also assessed using multivariate regression with adjustment for age group, sex, and treatment history. Analyses were repeated for a subset of patients with VL assessment from 12 to 30 weeks post-treatment.
resultsA total of 1707 (44 3D and 1663 SOF/LDV) patients were included. The majority (60%) were male, 49% were aged 55-64 years, and 97% were treatment-naïve 1 year prior to index. The unadjusted relative risk (RR) for achieving SVR in patients treated with SOF/LDV compared with 3D was 0.98%, 95% confidence interval (CI): 0.93-1.02. After adjusting for the baseline covariates, the RR was 0.98%, 95% CI: 0.94-1.03.
conclusionsIn this early view of real-world data, effectiveness of all-oral DAA regimens in HCV genotype 1 patients was concordant with results from registration trials. SVR rates were similar for the two regimens. Further studies are needed to confirm these results.
