標題: | Simple formulas for gauging the potential impacts of population stratification bias | 作者: | WEN-CHUNG LEE Wang L.-Y. |

However, case-control studies may suffer from bias due to population stratification. In this paper, the authors present simple formulas that can set a limit to the havoc population stratification bias can wreak (the lower and upper bounds of the confounding rate ratio and the upper bound of the type I error rate). The authors demonstrate applications of these formulas using two examples. The formulas can help researchers make more prudent interpretations of their (potentially biased) results. ?
