Intrarater reliability^* of the modified Localized Scleroderma Skin Severity index (mLoSSI) and its domains including surface area domain. All domains were assessed by 14 examiners on 39 cutaneous anatomic sites. Intraclass correlation coefficient (95% confidence interval) was used to assess intrarater agreement.
