Patient self-report of co-morbid conditions had varying levels of agreement with those derived from administrative data, ranging from substantial agreement for diabetes (κ = 0.79) to poor agreement for cardiac arrhythmia (κ = 0.14).
In separate validation and reliability studies, the questionnaire has shown substantial agreement for test-retest reliability and from low to substantial agreement for criterion validity [ 23, 24].
The reliability of cervical strength measures ranged from substantial to almost perfect agreement for the healthy group (ICC = 0.67 to 0.85), and from fair to substantial agreement for the neck pain group (ICC= 0.39 to 0.72).
The kappa values revealed a slight agreement for raters 1,3 and 4, a moderate agreement for rater 5 and a substantial agreement for rater 2. Only for rater 2, a kappa value significantly different from zero was observed.
The ICC and Kappa values for the former ranged from 0.49 to 0.74, indicating a moderate to substantial agreement and from 0.30 to 0.96, indicating a regular to excellent agreement, respectively.
There was a substantial agreement range from k=.883, (p<.01) to k=.943, (p<.01) between adjusted and unadjusted percentile classification for the subgroups of male and female babies and first born and later born ones.
According to Landis and Koch [ 16], the agreement was rated as follows: Kappa between 0 and 0.2 indicates slight agreement, between 0.21 and 0.4 fair agreement, between 0.41 and 0.60 moderate agreement, between 0.61 and 0.8 substantial agreement, and from 0.81 excellent agreement.
The data is in substantial agreement with that from similar studies, and shows that the condition Ca = We/Re = constant is not a global criteria for air entrainment by a plunging surface.
The ICC was 0.62 (95%CI: 0.38, 0.85) indicating substantial agreement but ranging from poor to substantial.
Corrected TEC values show substantial agreement with model predictions from the International Reference Ionosphere IRII) and the Paramaterized Ionospheric Model (PIM).
