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
Protease inhibitors (PIs) targeting the hepatitis C virus (HCV) NS3 protease, such as telaprevir, have significantly improved the sustained virologic response (SVR) rates of HCV genotype 1 antiviral therapy. Given the expanding antiviral therapy regimen, fast HCV PI resistance assays are urgently needed. In this view, we have developed a novel phenotypic resistance test for HCV PIs based on in vitro synthesis of patient-derived HCV NS3 protease and subsequent enzymatic testing in a fluorescent readout. The enzymatically active HCV NS3 proteases were synthesized from PCR-derived templates by an Escherichia coli S30 extract system. Tests of the protease genes with known mutations for telaprevir resistance showed that the phenotypic resistance test was fast, with a total turnaround time of <10 h, and was fully in agreement with the previous resistance results. The initial tests with 38 treatment-naive serum samples showed that the method was significantly less laborious and faster than currently available phenotypic resistance assays of HCV NS3 PIs.
