Multivariate analyses of LVMI and LVEFa

Independent VariablesβP
aLVMI, left ventricular mass index; LVEF, left ventricular ejection fraction; ANP, atrial natriuretic peptide; ln, logarithm (natural); BNP, brain natriuretic peptide. Because of the strong ANP-BNP collinearity (see Results) the predictive power of the two peptides for LVMI and LVEF was tested in separate multiple regression models. Data are standardized regression coefficient (β) and P values. Factors that did not contribute significantly to the models may be deducted from the description of the multivariable strategy adopted in this study (see Statistical Analyses section).
bMultiple R = 0.64; P = 0.0001.
cMultiple R = 0.63; P = 0.0001.
dMultiple R = 0.49; P = 0.0001.
eMultiple R = 0.52; P = 0.0001.
