Links between identified-victims, which occur if escape of one has led to rescue of others (as cluster of victims in single location or controlled-individuals across a network of locations), have implications for how the totality of victims of modern slavery is estimated. Information from identified-victims can help to identify densely or dangerously trafficked-routes. Vulnerability of victims is not ended by their liberation: evidence-based healthcare and other support protocols are needed to assist recovery and resilience. The evidence-base for national protocols would be enhanced if over half the identified-victims agreed to join a research-led cohort by which morbidity and mortality could be monitored; location notified if the participant was again in extremis; with DNA-sampling offered as means to re-unite trafficked family-members.

如果一个受害者的逃逸导致他人的抢救（例如，一个地点的受难者群体或一个地点网络中的受控制的个人集群），则被确定的受害者之间便存在联系，这对如何估计现代奴隶制受害者的总数具有影响。来自确定的受害者的信息可以帮助识别密集或危险的人口贩运路线。受害者的脆弱性并不能因为他们的解放而结束：需要循证的医疗保健和其他支持协议来帮助恢复和复原力。如果一半以上的被确定受害者同意参加由研究牵头的队列研究，可以监测发病率和死亡率，那么国家议定书的证据基础将得到加强；通知参与者是否再次处于极端状态；并提供了DNA采样作为重新统一被贩运家庭成员的手段。
