Boceprevir Plus Peginterferon Alfa-2a/Ribavirin in Treatment-Naïve Hepatitis C Virus Genotype 1 Patients: International Phase IIIb/IV TriCo Trial.
Article in Infectious diseases and therapy, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01591460 (An International, Multicenter, Open-Label Study Evaluating Sustained Virological Response and Safety With Boceprevir in Triple Combination Therapy With Peginterferon Alfa-2a), which is not on this map.

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.

Abstract
introductionBoceprevir was not previously studied with peginterferon alfa-2a/ribavirin in phase III trials in treatment-naïve chronic hepatitis C patients. The international phase IIIb/IV TriCo study was, therefore, designed to evaluate boceprevir in combination with peginterferon alfa-2a/ribavirin in treatment-naïve genotype 1 patients.
methodsA total of 165 treatment-naïve genotype 1 patients were assigned to boceprevir plus peginterferon alfa-2a/ribavirin therapy according to the label. All patients received a 4-week lead-in with peginterferon alfa-2a/ribavirin, after which boceprevir (2400 mg/day) was introduced. The total duration of treatment ranged from 28 to 48 weeks depending on the virological response at Weeks 4, 8, and 24, and on fibrosis status. The primary efficacy outcome was sustained virological response (SVR) [undetectable hepatitis C virus (HCV) ribonucleic acid (RNA) 12 weeks after actual end of treatment, SVR12].
resultsThe overall SVR12 rate was 81% (133/165, 95% confidence interval 74-86%). After 8 weeks of treatment, 61% of patients had undetectable HCV RNA, and 78 patients (47%) had an early response (undetectable HCV RNA at Weeks 8 and 24) and were eligible to stop all therapy at Week 28. Among early responders the SVR12 rate was 95% (74/78), and among patients with cirrhosis assigned to 48 weeks' treatment, the SVR12 rate was 67% (14/21). The overall relapse rate was 7% (10/143), and was 4% (3/77) among early responders. The most common adverse events were anemia (41%), neutropenia (32%), and dysgeusia (31%).
conclusionHigh SVR12 rates can be achieved with boceprevir plus peginterferon alfa-2a/ribavirin in treatment-naïve HCV genotype 1 patients, including patients with well-compensated cirrhosis. Treatment is well tolerated when label restrictions are taken into account. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Identifier: NCT01591460.
