Table 3 Kappa, level of agreement, standard error (Std. error) and 95% confidence interval (CI) values of EO and IO according to their extraction decisions with and without cephalogram
From: Influence of lateral cephalometric radiographs on extraction decision in skeletal class I patients
Kappa | Level of agreement | Std. error | CI 95% | |
|---|---|---|---|---|
EO vs. IO without cephalogram | 0.283 | Fair | 0.078 | 0.130-0.435 |
EO vs. IO with cephalogram | 0.309 | Fair | 0.073 | 0.165-0.453 |
EO with and without cephalogram | 0.529 | Moderate | 0.093 | 0.346-0.712 |
IO with and without cephalogram | 0.444 | Moderate | 0.082 | 0.283-0.605 |
