Table 4 Multivariate analysis including LA measurements and CHADS 2 /CHA 2 DS 2 -VASc parameters for prediction of TEE surrogate markers of stroke

From: Which method of left atrium size quantification is the most accurate to recognize thromboembolic risk in patients with non-valvular atrial fibrillation?
