Mosquito repellent test data from the literature were analyzed to estimate mean protection periods and among-subjects standard deviations. Standard deviations were a linear function of the means. Numbers of subjects needed to determine mean protection periods of 1-8 h with confidence limits of +/- 0.5, 1.0, 1.5, and 2.0 h at the 99 and 95% levels of confidence were computed from regression values of the standard deviation, and a table of sample sizes was constructed for use in planning repellent tests.
对文献中的驱蚊测试数据进行分析，以估算平均防护期和受试者间的标准差。标准差是均值的线性函数。根据标准差的回归值，计算出在99%和95%置信水平下，确定平均防护期为1至8小时且置信限为±0.5、1.0、1.5和2.0小时所需的受试者数量，并构建了一个样本量表格，用于规划驱蚊测试。
