Biochemical Rather than Virologic Response to Interferon Therapy may be More Closely Associated with Decrease of Hepatocellular Carcinoma Incidence in Patients with Chronic Hepatitis B.
Article in Gut and liver, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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/
aimsThe authors examined whether the response to interferon (IFN) therapy can affect the development of hepatocellular carcinoma (HCC) in chronic hepatitis B (CHB) patients.
methodsOut of 353 biopsy-proven CHB patients, 229 (65%) were treated with IFN-alpha for 6 to 12 months. They were followed for a median period of 75 months (range, 6-120). In patients treated with IFN, biochemical and virologic responses were evaluated at the end of treatment (EOT). The cumulative incidence rates of HCC were calculated and analyzed in relation to baseline characteristics as well as biochemical and virologic responses to IFN therapy.
resultsThe overall cumulative incidence of HCC was 0%, 0.8%, 3.7% and 5.5% at 3, 5, 7 and 8 years, respectively. Age, serum AFP levels and the stage of fibrosis were significantly associated with the occurrence of HCC. As a whole, IFN therapy did not affect the occurrence of HCC. Among the patients treated with IFN, biochemical responders had low HCC incidence rates compared with non-responders (p=0.018). However, the HCC incidence rates of virologic responders were not different from non-responders (p=0.203).
conclusionsBiochemical rather than virologic response to IFN therapy may be more closely associated with decrease of HCC incidence in CHB patients.
