Abstract

This community-based prospective study examined the effects of viral infections and lifestyle habits on hepatocellular carcinoma (HCC) risk in Japan. A baseline survey was conducted for 981 males and 2,078 females in June 1992 and evaluated hepatitis B surface antigen, second-generation hepatitis C virus antibody, and history of cigarette smoking and habitual alcohol consumption. By March 1997, 14 males and 8 females had been newly diagnosed with HCC. After controlling for gender and age by using the Cox model, the authors found that positivity for hepatitis B surface antigen (hazard ratio = 7.28, 95% confidence interval: 1.62, 32.61; p < 0.01) and positivity for high-titer hepatitis C virus antibody (hazard ratio = 40.38, 95% confidence interval: 11.71, 139.21; p < 0.001) were significantly associated with HCC risk, although a history of smoking or alcohol consumption was not significantly related to risk. There was a significant interaction on an additive scale for the risk of HCC development between high-titer hepatitis C virus antibody status and a history of smoking (p < 0.05) in spite of no significant interaction on a multiplicative scale. Although preventing the transmission of hepatitis viruses is most important for reducing the risk of HCC, intervention regarding lifestyle habits such as cigarette smoking should not go unheeded.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Exposure fractions among prevalent liver cirrhosis cases were used as a proxy for population attributable fractions, following the direct method when relative risk is high.

    “We used the resulting predicted exposure fractions among prevalent cases as a proxy for PAFs for liver cirrhosis. This follows from the direct method of approximating PAFs:”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
