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
Introduction: In chronic hepatitis C virus (HCV) patients in whom prior direct-acting antiviral agent (DAA) treatment had failed, outcomes after retreatment are optimal. Combination of sofosbuvir (SOF), daclatasvir (DCV), simeprevir (SIM), and ribavirin (RBV) in treatment experienced patients is recommended in current guidelines despite insufficient data. Our aim is to determine the efficacy and safety of SOF, DCV, SIM plus RBV in HCV infected patients who failed prior DAA treatment. Material and methods: One hundred and seventeen patients who failed to respond to SOF containing regimens were randomized according to previous response to therapy to non-responders and relapsers. Duration of therapy depends on fibrosis stages. SOF, DCV, SIM and weight based RBV 12 weeks for F1 and F2 (group I) and 24 weeks for F3 and F4 (group II). Results: In the non-responder group, a sustained virologic response (SVR) occurred in 100% in group I (F1 and F2) and 97% in group II (F3 and F4). Relapse was 3% in group II (F3 and F4). No patients from either group had breakthrough or non-response. In relapsers SVR was 100% in group I (F1 and F2) and 96% in group II (F3 and F4). Breakthrough, relapse and non-response were 2%, 4%, 2% respectively only in group II (F3 and F4). Conclusions: Combining multiple DAAs with different viral targets may be effective treatment protocol in previous non-responders and relapsers with short durations of treatment.
