No significant association was found between T-cell reactivity and the variables in Table 2 , but it is worth mentioning that a near-significant correlation was found between t-cell reactivity and the mean urea level before dialysis during the study period ( p = 0.054) and that there was a tendency that patients with diabetes (n = 23) more often had a negative T-cell response ( p = 0.085).
