CRP and Epstein-Barr virus infection: In the univariate Cox regression analysis, several factors were identified as significant risk factors for the development of DPTM, including older age at the time of kidney transplant (HR 1.59, 95%CI: 1.34–1.88, p < 0.001), higher median C-reactive protein (CRP) levels (HR 1.02, 95%CI: 1.01–1.02, p < 0.001), and EBV infection (HR 2.09, 95%CI: 1.28–3.41, p = 0.003) (Supplementary Table S3).
