Consistency in the radiological and histopathological diagnosis of anti-MDA5+DM ILD
| Radiological pattern | Histopathological pattern | Total | ||||
| NSIP | OP | NSIP+OP | DAD | AFOP | ||
| NSIP | 0 | 0 | 1 | 0 | 0 | 1 |
| OP | 4 | 0 | 5 | 0 | 1 | 10 |
| NSIP+OP | 3 | 0 | 2 | 1 | 0 | 6 |
| Total | 7 | 0 | 8 | 1 | 1 | 17 |
% agreement: 11.8%; kw=−0.098 (95% CI −0.325 to 0.128), p=0.416.
% agreement was calculated by adding the concordant percentages.
See table 2 for other definitions.
