Multiple line regression analysis of corneal stiffness and highest concavity parameter.

Dependent variable	Independent variable	Standardized regression coefficient
SP-A1	Pre-PDHC	−0.38	0.460
	Pre-HCR	−0.06	0.709
	Pre-DAHC	0.58	0.264
	Pre-HCT	0.37	0.032
SSI	Pre-PDHC	−0.21	0.700
	Pre-HCR	0.22	0.221
	Pre-DAHC	0.33	0.550
	Pre-HCT	0.29	0.107

All the independent variable from liner regression analysis were included in the model. PDHC: highest concavity peak distance; DAHC: highest concavity def amp. HCR: HCR: highest concavity radius; HCT: highest concavity time; SP-A1: stiffness parameter A1, SSI: stress-strain index. Liner regression analysis of different independent variable with .
