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

BACKGROUND AND

aimsThe risk of hepatocellular cancer (HCC) after sustained virological response (SVR) with direct-acting antivirals (DAA) is unclear. Our aim was to examine the risk and determinants of HCC in patients cured with DAA.

methodsWe conducted a retrospective cohort study of hepatitis C virus patients who were treated with DAA in any of the 129 Veterans Health Administration hospitals between January 1, 2015 and December 31, 2015. We calculated the annual incidence rates of HCC by SVR. We used Cox regression models to compare the risk of HCC in patients with vs those without SVR and to identify factors associated with incident HCC among patients with SVR. We reviewed a sample of HCC patients for tumor size and stage at diagnosis.

resultsAmong 22,500 patients treated with DAA (19,518 with SVR; 2982 without SVR), the mean (standard deviation) age was 61.6 (6.1) years, and 39.0% had cirrhosis. There were 271 new cases of HCC, including 183 in patients with SVR. Compared with patients without SVR, those with SVR had a significantly reduced risk of HCC (0.90 vs 3.45 HCC/100 person-years; adjusted hazard ratio, 0.28, 95% CI=0.22-0.36). Patients with cirrhosis had the highest annual incidence of HCC after SVR (1.82 vs 0.34/100 person-years in patients without cirrhosis; adjusted hazard ratio, 4.73. 95% CI, 3.34-6.68). Most (>44.8%) HCC were classified as stage I. Maximum size of the largest lesion was ≤5 cm in over 75% of cases.

conclusionsAmong patients treated with DAA, SVR was associated with a considerable reduction in the risk of HCC. We did not find any evidence to suggest that DAAs promote HCC. However, in patients with SVR, the absolute risk of HCC remained high in patients with established cirrhosis. These patients should be considered for ongoing HCC surveillance.
