Note: “c” indicates that patients were divided into negative MAC (MAC score = 0, n = 220), lower MAC score (0 < MAC score ≤ 268, n = 40) and higher MAC score (MAC score > 268, n = 40) subgroups.
Abbreviations: AF, atrial fibrillation; AS, aortic stenosis; CI, confidence interval; LADD, left atrial end‐diastolic dimension; MAC, mitral annular calcification; MS, mitral stenosis; OR, odds ratio; VIF, variance inflation factor.
