Assessment of the inter-rater reliability between two physicians
| Causality | 87 patients |
|---|---|
| Agreement | 84% |
| Positive agreement | 87% |
| Negative agreement | 80% |
| κ statistic (95% CI) | 0.67 (0.51 to 0.83) |
| Preventability | 45 patients |
| Agreement | 84% |
| Positive agreement | 87% |
| Negative agreement | 80% |
| κ statistic (95% CI) | 0.67 (0.45 to 0.90) |
To assess the reliability of the preventability, the sample size population contained an over-representation of AEs compared with the whole MI study population (AE:non-AE ratio is 2:1).
AE, adverse event; MI, myocardial infarction.
