Efficient Hepatitis C Virus Genotype 1b Core-NS5A Recombinants Permit Efficacy Testing of Protease and NS5A Inhibitors.
Article in Antimicrobial agents and chemotherapy, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Hepatitis C virus (HCV) strains belong to seven genotypes with numerous subtypes that respond differently to antiviral therapies. Genotype 1, and primarily subtype 1b, is the most prevalent genotype worldwide. The development of recombinant HCV infectious cell culture systems for different variants, permitted by the high replication capacity of strain JFH1 (genotype 2a), has advanced efficacy and resistance testing of antivirals. However, efficient infectious JFH1-based cell cultures of subtype 1b are limited and comprise only the 5' untranslated region (5'UTR)-NS2, NS4A, or NS5A regions. Importantly, it has not been possible to develop efficient 1b infectious systems expressing the NS3/4A protease, an important target of direct-acting antivirals. We developed efficient infectious JFH1-based cultures with genotype 1b core-NS5A sequences of strains DH1, Con1, and J4 by using previously identified HCV cell culture adaptive substitutions A1226G, R1496L, and Q1773H. These viruses spread efficiently in Huh7.5 cells by acquiring additional adaptive substitutions, and final recombinants yielded peak supernatant infectivity titers of 4 to 5 log
