Fig. 2

In this figure the representation of cumulative survival events free curves for study endpoints, by Cox regression analysis curves. The figure is structured in seven parts, as a–f, Fig. 3. In green color the bipolar group, in blue color the multipolar group for each figure part. The symbol asterisk was marking a statistical significant event, as indicated by a p value <0.05. In the part a of the figure, the curve representation of Phrenic Nerve stimulation events as “cumulative risk for Phrenic Nerve stimulation” (on y axis) during 360 days follow up (on x axis) comparing multipolar vs bipolar group. In the part b of the figure, the curve representation of catheter dislocation events as “cumulative risk for catheter dislodgement events” (on y axis) during 360 days follow up (on x axis) comparing multipolar vs bipolar group. In the part c of the figure, the curve representation of re-interventions for left ventricle lead re-positioning after dislodgment as “cumulative risk for re-interventions for left ventricle catheter re-positioning” (on y axis) during 360 days follow up (on x axis) comparing multipolar vs bipolar group. In the part d of the figure, the curve representation of hospital admission events as “cumulative risk for hospital admissions events” (on y axis) during 360 days follow up (on x axis) comparing multipolar vs bipolar group. In the part e of the figure, the curve representation of atrial fibrillation events as “cumulative risk for atrial fibrillation events” (on y axis) during 360 days follow up (on x axis) comparing multipolar vs bipolar group. In the part f of the curve, the representation of all cause of deaths events as “cumulative risk for all cause of deaths events” (on y axis) during 360 days follow up (on x axis) comparing multipolar vs bipolar group
