Mean prevalence of findings among the 4 raters (95% CI) unless otherwise specified. Intrarater and interrater reliability by Cohen’s κ. Twenty-two subjects with JIA examined by 4 raters.
↵* The prevalence is calculated as an average value of the findings of the 4 raters.
↵** Continuous data and calculated as an intraclass correlation coefficient. TMJ: temporomandibular joint; JIA: juvenile idiopathic arthritis.
