我们调查了德国基于人群的病例对照研究的招募方法、应答水平和决定因素，以及应答比例的计算方法。我们确定了26项符合条件的研究。合并分析显示，对照组应答率为68%，病例应答率为80%。没有电话的对照组的应答比例比有电话的对照组低50%左右。我们提出了一个新的衡量指标，表明招聘策略的有效性。
We investigated the methods of recruitment, levels and determinants of response, and the calculation method of response proportions in population-based case control studies in Germany. We identified 26 eligible studies. The pooled analysis showed that the response proportion was 68% among controls and 80% among cases. Response proportions among controls without telephones were about 50% lower than for controls with telephones. We propose a new measure that indicates the efficacy of the recruitment strategy.
