  1. *P<0.05
  2. LAD Left atrial diameter, LAT/SEC Left atrial thrombosis/spontaneous echo contrast, Lp(a) Lipoprotein (a), OR Odds ratio, CI Confidence interval
  3. Model I adjusted for gender and age. Mode II adjusted for gender, age, non-paroxysmal atrial fibrillation, smoke, history of coronary heart disease, diastolic blood pressure, prothrombin time, D-Dimer, fibrinogen, NT-proBNP, left atrial diameter, left ventricular ejection fraction, and interventricular septal amplitude. For the Lp(a) group: Q1: Lp(a) ≤ 91.5 mg/L; Q2: 91.5 < Lp(a) ≤ 164 mg/L; Q3: 164 < Lp(a) ≤ 266 mg/L; Q4: Lp(a) > 266 mg/L. For the LAD group: Q1: LAD ≤ 31 mm; Q2: 31 < LAD ≤ 35 mm; Q3: 35 < LAD ≤ 39.5 mm; Q4: LAD > 39.5 mm
