Data are expressed as correlation coefficient (r) and p value. Using Pearson or Spearman correlation analysis is based on the distribution and type of the data. Significant correlations are indicated in bold.
BMI, body mass index; CRP, C-reactive protein; iPTH, intact parathyroid hormone; BNP, B-type natriuretic peptide; LVEF, left ventricular ejection fraction; LAVI, left atrial volume index; LVEDVI, left ventricular end-diastolic volume index; LVESVI, left ventricular end-systolic volume index; LVMI, left ventricular mass index; e′, early diastolic mitral annular velocity; E/A, early to atrial filling velocity; E/e′, ratio of the early transmitral flow velocity to early diastolic mitral annular velocity.
