  1. The effects of measurement error on previously reported mathematical relationships between indicator organism density and swimming-associated illness : a quantitative estimate of the resulting bias.

    Article - En anglais

    The results of the computer simulations show that the bias caused by this measurement error is non-differential causing the mathematical relationships between indicator organism density and swimming-associated illness reported in previous epidemiological studies to underestimate true risk by a minimum of approximately 14%, and that this underestimate could range as high as approximately 30 to 57%. This study also demonstrates that substantial reduction of this bias can be easily accomplished by incorporating a formal water quality sampling strategy.
