Community‐informed and codesigned research to understand the impacts of railways on wildlife
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Trains cause mortalities of several animal species, but the ecological impacts of railways are understudied. Most research on wildlife–train collisions has focused on large mammals, but understanding railway‐specific risks for underrepresented taxa, especially vulnerable species, is important for developing effective mitigation strategies ...

Application of competing risk model in the prognostic prediction study of female breast cancer [PDF]
, 2016 目的探索竞争风险模型在乳腺癌患者预后预测中的应用,并与传统生存分析结果进行比较。方法运用K-M方法估算总体风险率;采用原因别风险模型进行多因素分析,评价复发和转移的影响因素。结果 K-M方法的风险率高于竞争风险情况下的风险率。肿瘤大小和个人乳腺疾病史是复发的独立预后因素。结论竞争风险模型在乳腺癌患者的预后预测中更合理、更客观。Objective To explore the application of competing risk model in the prognostic prediction ...
