  1. According to Altman, kappa (κ) values between 0.4 and 0.6 refer to moderate agreement. Consistency was evaluated by comparing the number of discordant results using the McNemar’s Test (p < 0.05 was considered statistically significant). Of note, assessment does not take into consideration indeterminate results of the QuantiFERON®-CMV assay. CI confidence interval
