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
BACKGROUND AND
objectivesWe studied the effect of achieving sustained virological response (SVR) on the risk of developing hepatocellular carcinoma (HCC) in patients with hepatitis C receiving anti-hepatitis C virus treatment. Avoiding HCC is considered the main long-term benefit of successful antiviral treatment.
methodsOur literature search extended up to June 2015. We identified all studies that assessed the risk of HCC in patients achieving or not achieving SVR. Meta-analysis was based on a standard random-effect model. The end-point was occurrence of HCC compared between patients with and without SVR; this end-point was expressed as an odds ratio and percent reduction in risk and was also presented separately for patients with and without cirrhosis. All results estimates presented with 95 % confidence intervals (CIs). The presence of any temporal trend in these indexes was investigated by standard meta-regression.
resultsOur search identified 25 observational studies (19,822 patients). The odds ratio of HCC for SVR versus no-SVR was 0.19 (95 % CI 0.15-0.24) in the overall series of 25 studies. The difference in this index between patients with any stage of fibrosis/cirrhosis and those with cirrhosis was small. With regard to risk difference, the 25 studies indicated an overall reduction of 10 % (95 % CI 8.00-12.0); this effect was much less pronounced in the group with any stage of fibrosis/cirrhosis (risk difference 6.7 %) than in the selected group with cirrhosis (risk difference 22 %). Meta-regression showed no temporal trend.
conclusionOur analysis was successful in providing an updated overview on this controversial topic. Some pharmacoeconomic assessments are also presented to interpret the clinical results of our analysis.
