Table 1

Fundamental statistics and interrater reliability for the areas of retinal hemorrhage measured by using a grid with 14 squares and empty box.

	Sample size	Grid with 14 squares			Empty box
		Avg.	SD	SE	Avg.	SD	SE
Rater 1	30	31.27	20.27	3.70	43.50	22.48	4.10
Rater 2	30	29.10	18.66	3.40	43.33	20.69	3.78
Rater 3	30	28.50	18.27	3.33	38.83	18.23	3.33
Sum	90	29.63	18.91	1.99	41.89	20.42	2.15
ICC		0.96			0.78

Avg., average; SD, standard deviation; SE, standard error; ICC, intraclass correlation coefficient.
