Specific criteria are given for several methods of determining the basal body temperature shift. The specific criteria selected have been coded for a uniform interpretation by computer, and interpretations have been compared for 8496 charts. Our results indicate that the method that defines the temperature shift as 0.3 degrees F or more above the running low average for at least 3 consecutive days provides the best concurrent chart interpretation method. A method that creates a smoothed curve that transects the average of all temperatures on a completed graph provides a good retrospective method for identifying the temperature shift. Both the temperature averaging technique and curve smoothing technique identified a temperature shift in more than 95% of the charts with complete temperature readings.
文中给出了几种确定基础体温变化的方法的具体标准。所选择的具体标准已进行编码，以便计算机进行统一解读，并对8496份图表的解读结果进行了比较。我们的结果表明，将体温变化定义为比连续至少3天的运行低平均体温高0.3华氏度或更多的方法，提供了最佳的同步图表解读方法。一种创建平滑曲线并与完整图表上所有温度的平均值相交的方法，为识别体温变化提供了一种很好的回顾性方法。温度平均技术和曲线平滑技术在95%以上有完整温度读数的图表中都识别出了体温变化。
