This paper presents the results of a study with a two-occasion capture-recapture design. The data are part of the AjUDE-Brasil II Project, carried out in 2000-2001. Estimation of the size of the IDU population attending a syringe-exchange program (SEP) in São José do Rio Preto, Salvador, and Porto Alegre, Brazil, was performed using Chao's model. Capture probabilities were also estimated. For Porto Alegre a comparison of the results from the AjUDE-Brasil I and AjUDE-Brasil II Projects was performed. Results are also presented for error rates secondary to the choice of matching criteria.
本文介绍了一项采用两阶段捕获-再捕获设计的研究结果。这些数据是2000 - 2001年开展的巴西阿茹德二期项目的一部分。使用Chao模型对巴西里约普雷图河畔圣若泽、萨尔瓦多和阿雷格里港参加注射器交换项目（SEP）的注射吸毒者群体规模进行了估计。还对捕获概率进行了估计。对阿雷格里港的巴西阿茹德一期和巴西阿茹德二期项目的结果进行了比较。还给出了因匹配标准选择而产生的错误率结果。
