  1. PPV positive predictive value; NPV negative predict value; PLR positive likelihood ratio; NLR negative likelihood ratio
  2. aThe agreement was good (kappa value ≥ 0.75); moderate (0.4 ≤ kappa value < 0.75); poor (kappa value < 0.4); meaningless (kappa value < 0)
  3. bIf p < 0.05, the agreement is significant
