Table 3 Analysis of Cohen’s Kappa for the un-dichotomized modified Rankin scale values. Linear weights were used for the weighted Kappa analysis
Kappa method | Kappa value, (95% CI) | p-Value | Strength of agreement | Identical scores |
|---|---|---|---|---|
Linear weighted | 0.82 (0.75–0.90) | < 0,001 | very good | 87/108 (80.6%) |
Unweighted | 0.73 (0.63–0.84) | < 0,001 | good | 87/108 (80.6%) |
