In the absence of well-controlled studies on the clinical effectiveness of condoms against pregnancy and sexually transmitted diseases, breakage and slippage data may provide the best indication of the protection offered by condom use. According to the recent literature, condom breakage rates range from 0% to 12%, with many US studies falling in the 2% to 5% range. Few studies have collected slippage data. In addition to discussing methodological issues associated with these studies, we propose a standardized protocol for future condom breakage and slippage trials and discuss how results may be used to estimate perfect-use and typical-use pregnancy rates.
由于缺乏关于避孕套预防怀孕和性传播疾病临床有效性的严格对照研究,破损和滑落数据可能是使用避孕套提供保护的最佳指标。根据最近的文献,避孕套破损率在0%至12%之间,许多美国研究的数据落在2%至5%的范围内。很少有研究收集滑落数据。除了讨论与这些研究相关的方法学问题外,我们还提出了未来避孕套破损和滑落试验的标准化方案,并讨论如何利用结果来估计完美使用和典型使用情况下的怀孕率。
