Title: Risk of AF according to LAVmin in patients with normal size LA
Caption: X-axis displays follow up time, Y-axis displays the probability of staying AF free. The plot is stratified by high LAVmin and low LAVmin, with the cutoff being 11 mL/m2. The solid blue line represents the likelihood of staying AF free for the low LAVmin subgroup and the light blue area is the 95 % confidence interval. The solid red line represents the likelihood of staying AF free for the high LAVmin subgroup and the light red area is the 95 % confidence interval. The graph displays a statistically significant lower probability of staying AF free for the subgroup with high LAVmin (p value for log rank= 0.02). Data is plotted for patients with LAVI < 34 mL/m2 .
LAVmin: Left atrium minimal volume , AF: Atrial fibrillation, HR: Hazard Ratio
