The univariate and multivariate regression model results for left ventricle strain.

Variables	R2	p Value	B Unstandardised	p Value
Age	−0.2	0.01
BSA	−0.24	0.002
SBP	−0.22	0.005
LV Mass	−0.22	0.005
DDLV	−0.2	0.01
EDV	−0.25	0.001	−0.032	0.001

R²: Determination coefficient, BSA body surface area, SBP systolic blood pressure, LV left ventricle, DDLV end diastolic diameter of left ventricle, EDV end diastolic volume, LVEF left ventricular ejection fraction biplane by Simpson. Variables that reached p-values < 0.01 in the univariate model and did not show collinearity with other variables (VIF < 5) were included in the multivariate model. In cases of collinearity, the variable with the highest correlation coefficient was included in the multivariate model. If a variable included in the multivariate model did not reach statistical significance, it was excluded by backward steps. r = 0.322, R² = 0.104 and corrected 0.091 for the multivariate regression model, p: 0.001. Bold value indicates p-values < 0.01.
