Agreement intraclass correlation coefficient to assess reliability of the trained graders as a group for grading of fungal keratitis.

Variable	Mean of 5 student graders, ICC (95% CI)
Opacity	0.86 (0.81–0.90)
Hypopyon	0.92 (0.89–0.94)
Location	0.90 (0.87–0.93)
Percent in inner circle	0.93 (0.91–0.95)
Inflammation	0.90 (0.87–0.93)
Neovascularization	0.76 (0.69–0.81)
Area	0.92 (0.89–0.94)
Area (transformed)	0.93 (0.89–0.95)
Ulcer visibility	0.87 (0.83–0.90)

Both area and square root of the area are reported.

CI, confidence interval; ICC, intraclass correlation coefficient
