Reliability metric | Intra- or inter-rater? | Number of values (studies) | Reliability metric | Average reliability value | Range | Confidence in PRL reliability, average (range) |
---|---|---|---|---|---|---|
Per-lesion rim presence | Intra | 3 (2) | Cohen’s κ | 0.833 | 0.77 – 0.96 | “Near perfect” (“Substantial” to “Near Perfect”) |
Inter | 7 (6) | Cohen’s κ | 0.687 | 0.43 – 0.87 | “Substantial” (“Moderate” to “Near perfect”) | |
Per-subject PRL number | Inter | 4 (4) | ICC | 0.874 | 0.796 – 0.96 | “Good”(“Good” to “Excellent”) |
ICC – intraclass correlation coefficient; PRL – paramagnetic rim lesion.
