Univariate and multivariate analyses with left ventricular mass index as the outcome variable.

a24-hour systolic blood pressure was used as the strongest correlating variable representing blood pressure in the model. Data analysed using Pearson correlation (univariate) and enter linear regression (multivariate). All variables that correlated significantly with left ventricular mass index in univariate analysis were entered into the multivariate regression model. R2 for model = 0.46, P
