Analysis of data from Japan and Hawaii offers no support for the hypothesis that the use of talc-coated rice increases the risk of developing stomach cancer. This conclusion is based on the observation that Japanese in Japan have very high rates of stomach cancer but consume no talc-coated rice, that Japanese in Hawaii have intermediate rates of stomach cancer but consume considerable amounts of talc-coated rice, and that Filipinos in Hawaii have very low rates of gastric cancer but consume the highest amounts of talc-coated rice of these three groups. Furthermore, secular trends in gastric cancer incidence show a much greater decrease in the incidence of this tumor among the exposed Japanese in Hawaii than among the unexposed Japanese in Japan.
对来自日本和夏威夷的数据进行分析后，没有发现任何证据支持食用滑石粉涂层大米会增加患胃癌风险这一假设。这一结论基于以下观察结果：在日本的日本人胃癌发病率很高，但不食用滑石粉涂层大米；在夏威夷的日本人胃癌发病率处于中等水平，但食用大量滑石粉涂层大米；在夏威夷的菲律宾人胃癌发病率很低，但在这三组人群中食用滑石粉涂层大米的量却是最多的。此外，胃癌发病率的长期趋势表明，在夏威夷接触滑石粉涂层大米的日本人中，该肿瘤发病率的下降幅度比在日本未接触的日本人中要大得多。
