Average reliability values calculated from literature values and our single-center study.

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.
