A:ROC curve analysis revealed that the AUC values of platelet count(PLT),hemoglobin level(Hb),and albumin level(Alb)for diagnosing terminal
ileum lesions as Crohn's disease(CD)were 0.71,0.76,and 0.74,respectively.B:ROC curve analysis demonstrated that the AUC values of the neutrophil⁃to⁃
lymphocyte ratio(NLR)and platelet⁃to⁃lymphocyte ratio(PLR)for diagnosing terminal ileum lesions as Crohn's disease(CD)were 0.69 and 0.75,
respectively.C:ROC curves illustrating the combined diagnostic performance of platelet count(PLT),hemoglobin level(Hb),albumin level(Alb),
neutrophil⁃to⁃lymphocyte ratio(NLR),and platelet⁃to⁃lymphocyte ratio(PLR)for terminal ileum lesions as Crohn's disease(CD).

及时治疗、预防及控制并发症的重要性 [24] 。目前 王璐、王舒、林俊杰和张红杰提供研究思路,指导数据分析;
相关研究已提出了早期 CD 的概念 [25] ,旨在尽早干 马晶晶负责研究的整体指导和论文的修改完善。
