1 · What the graph read from 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.

2 · The registry

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

backgroundChronic hepatitis C virus (HCV) infection is one of the leading causes of hepatic cirrhosis and hepatocellular carcinoma, and HCV genotype 1 is the most prevalent genotype and is resistant to current standard therapy. We performed this meta-analysis to evaluate the efficacy and safety of telaprevir-based therapy for chronic HCV genotype 1 infection.

methodsWe included randomized controlled trials with no year or language restriction. All data were analyzed using a random-effects model by Review Manager v5.0. The primary outcome was the proportion of patients achieving sustained virologic response (SVR), and the secondary outcomes were HCV relapse rate, incidence of severe adverse events (SAEs), and discontinuation due to adverse events.

resultsThe proportion of achieving SVR was significantly higher in the telaprevir group (odds ratio [OR] =3.40 [1.92, 6.00], P<0.0001; I(2) =87%) regardless of a patients' previous treatment status. It was also significantly higher in the 24-week and 48-week treatment groups (OR=4.52 [2.08, 9.81], P<0.001; I(2) =85%, and OR=4.05 [1.56, 10.56], P=0.004; I(2) =92%, respectively), while it was comparable in the 12-week treatment group (OR=1.32 [0.63, 2.75], P=0.46; I(2) =35%). In addition, the HCV relapse rate was significantly reduced in the telaprevir group (OR=0.28 [0.16, 0.49], P<0.001; I(2) =76%). However, the incidence of SAE (OR=1.56 [1.15, 2.10], P=0.004; I(2) =0%) and study discontinuation due to adverse events (OR=2.24 [1.43, 3.50], P<0.001; I(2) =37%) were significantly higher in the telaprevir group.

conclusionDespite its higher incidence of SAEs and discontinuation due to adverse events, telaprevir-based therapy can increase the proportion of achieving SVR in both previously treated and untreated chronic HCV-1 infected patients.
