Repeatability Test for Central Subfield Thickness Measurements: COV and ICC

Types of Scans	No. of Scans	Average COV	ICC	LB	UB
Both	197	8.0%	0.82	0.76	0.86
Line scans	126	5.9%	0.90	0.83	0.95
Star scans	116	7.8%	0.82	0.57	0.93

COV, coefficient of variation; ICC, intraclass correlation coefficient; LB, lower boundary; UB, upper boundary
