This report compares validity, precision and convenience of three frequently used parameters used to describe seasonality in reproductive outcome: prevalence, index and ratio observed versus expected. Each has its advantages and disadvantages; the choice of the parameter depends on the aim of the study. It is advisable to report the number of cases and referents per month, because all three parameters can be derived from this information.
本报告比较了用于描述生殖结局季节性的三个常用参数的有效性、精确性和便利性：患病率、指数以及观察值与预期值之比。每个参数都有其优缺点；参数的选择取决于研究目的。建议报告每月的病例数和对照数，因为所有这三个参数都可从这些信息中得出。
