Multivariate logistic regression analysis for the presence of atrial arrhythmia at 24-week follow-up.

Multivariate logistic regression analysis for atrial arrhythmia rate
Factors	P-value	OR	95% CI for OR
Perioperative medications
ARNI	P = 0.014	0.109	0.019–0.635
Statin	P = 0.039	0.200	0.044–0.919
Preoperative anti-arrhythmic drugs
Amiodarone	P = 0.174	8.341	0.392–177.276
Medical history
Persistent AF	P = 0.417	2.127	0.344–13.161
Diabetes mellitus	P = 0.601	0.666	0.145–3.056
Stroke/TIA	P = 0.441	0.491	0.081–2.998
Baseline clinical data
SBP (mmHg)	P = 0.287	1.027	0.978–1.079
Serum potassium (mmol/L)	P = 0.136	4.976	0.605–40.939
Baseline UCG
LAD (mm)	P = 0.565	0.955	0.816–1.117
LVEDD (mm)	P = 0.670	1.032	0.894–1.190
LVEF (%)	P = 0.847	0.992	0.917–1.073

Factors with P < 0.2 in the univariate logistic regression analysis, factors that differed between the two groups at baseline and factors commonly considered to be associated with atrial electrical instability in clinic were included in the multivariate logistic regression analysis. ARNI and Statins were independently associated with the presence of atrial arrhythmia at 24-week follow-up (P < 0.05) in multivariate logistic regression analysis.

OR, odd ratio; CI, confidence interval; AF, atrial fibrillation; TIA, transient ischemia attack; SBP, systolic blood pressure; LAD, left atrium diameter; LVEDD, left ventricle end-diastolic diameter; LVEF, left ventricle ejection fraction.
