Categorical variables were compared with the chi-square test, and continuous variables were compared with either the Mann-Whitney U test or the Student's t test, as appropriate. Correlation analysis was performed using the Pearson test. Age, gender, smoking status, body mass index, serum creatinine, hemoglobin, white blood cell count, cholesterol, LVMI, LAVI, diastolic dysfunction, anti-hypertensive medication, SBP, DBP and PP were tested in univariate linear regression analysis. Multivariate regression analysis including all variables associated in univariate analysis (p<0.2) was used to identify predictors of inter- and intra-atrial EMD.
