via cox proportional hazards analysis, there was no significant difference in positive CMV specific T cell immune responses between KT recipients from HCV viremic donors versus HCV aviremic donors (for CD8+: HR = 1.072, 95%CI: 0.458–2.507; p = 0.561; for CD4+: HR = 1.210, 95%CI: 0.526–2.784; p = 0.654) adjusted for recipient age, gender, race and diabetes mellitus (Tables 2 and 3). Here, CD8A is linked to diabetes mellitus.
