In this study, we evaluated the reproducibility of analysis of basal body temperature graphs under optimized conditions for agreement. A total of 160 recordings were selected from spontaneous cycles of infertile women and analysed by three experienced clinicians using uniform criteria. Agreement at the various stages of analysis was assessed by the 'proportions of agreement' with 95% confidence intervals. Agreement in identification of the thermal nadir was clearly superior to that reported in previous publications. Reproducibility of 'ovulatory' graph features (i.e. biphasic graphs and adequate thermal shifts) was excellent. Agreement in classification of monophasic graphs and inadequate thermal shifts, although lower, was still good. Thus, with experienced observers and uniform criteria, a good agreement can be achieved in analysis of the most important parameters of the basal body temperature graph. We believe that an effort should be made to generalize the use of uniform analysis criteria, because only then can results from different institutions be compared and the remaining clinical evaluation of the method be performed.
在本研究中，我们评估了在优化的一致性条件下基础体温图分析的可重复性。从不孕女性的自然周期中选取了总共160份记录，并由三位经验丰富的临床医生使用统一标准进行分析。通过“一致性比例”及95%置信区间评估分析各阶段的一致性。热谷最低点识别的一致性明显优于以往出版物中报道的情况。“排卵型”图特征（即双相图和足够的体温变化）的可重复性极佳。单相图和体温变化不足的分类一致性虽然较低，但仍良好。因此，有经验丰富的观察者和统一标准，在基础体温图最重要参数的分析中可以实现良好的一致性。我们认为应努力推广统一分析标准的使用，因为只有这样才能比较不同机构的结果并对该方法进行其余的临床评估。
