Table 3

Comparison of variables pertaining to the corneal thickness and endothelial characteristics between male and female in normal Chinese children and youngsters.

Parameters	Male ()	Female ()	-test	value
CCT (μm)			0.248	0.618
ECD (cells/mm^2)			0.851	0.356
CV (%)			2.891	0.089
HEX (%)			0.990	0.320
(S/μm^2)			0.481	0.488
(S/μm^2)			1.032	0.310
(S/μm^2)			3.188	0.074
(S/μm^2)			0.019	0.891

Note: SD: standard deviation; CCT: central corneal thickness; ECD: endothelial cell density; CV: coefficient of variation in cell area; HEX: hexagonal cells; : size of minimal cell; : size of maximal cell; : average cell size; : size standard deviation.
