a
Proportions of agreement P(A).
b
Kappa corrects for the eventuality that agreement could occur by chance alone.
c
Test marginal homogeneity between ratings of occurrence of anxiety among patients versus health-care professionals.
d
Agreement between the patients’ and the health-care professionals’ scoring of intensity of anxiety by using VAS was evaluated with single-measure intra-class correlation (ICC).
